    Title
    Glib2: toctou symlink race in `g_file_create_replace_destination` fallback path
    Summary
    A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.

    CVE-2026-19843 (GCVE-0-2026-19843)

    Vulnerability from nvd – Published: 2026-09-07 14:14 – Updated: 2026-09-07 14:14

    Title
    389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor
    Summary
    A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host.

    Title
    389-ds-base: 389-ds-base: sasl plain authentication allows privilege escalation to directory manager via stale identity in cyrus sasl auxiliary property
    Summary
    A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority without any valid credentials. A variant using a valid low-privileged account's own successful bind instead of an anonymous one is also possible.

    Title
    389-ds-base: 389-ds-base: pre-authentication null pointer dereference via paged results and use_one_backend control in op_shared_search
    Summary
    A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.

    Title
    389-ds-base: 389-ds-base: heap buffer overflow via sasl wrapped-record length lower-bound underflow in sasl_io_start_packet()
    Summary
    A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF > 0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow.

    Title
    389-ds-base: 389-ds: anonymous ldap client can defeat selfdn aci bind-rule checks via empty bind dn
    Summary
    A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user.

    Title
    Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service
    Summary
    A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.

    CVE-2026-76578 (GCVE-0-2026-76578)

    Title
    Ipa: freeipa: freeipa: unauthenticated ldap client can obtain administrator credentials via the self-managed-token aci
    Summary
    A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.

    Title
    Flatpak: flatpak: toctou race condition allows symlink redirection
    Summary
    A flaw was found in Flatpak. A Time-of-check to time-of-use (TOCTOU) race condition exists in the `org.freedesktop.Flatpak.SystemHelper` component. This vulnerability occurs because a privileged `chmod` operation executes before the OSTree repository validation within the `Deploy()` function. An attacker can exploit this timing window to redirect symlinks to arbitrary files, potentially leading to unauthorized file manipulation or information disclosure.

    Title
    Libsoup: libsoup: http/2 client crash in on_data_source_read_callback when settings initial_window_size shrinks during deferred body read
    Summary
    A flaw was found in libsoup. When a client sends an HTTP/2 request body from a non-pollable input stream, the library can buffer more data than the current flow-control window later allows. A malicious HTTP/2 server can shrink SETTINGS_INITIAL_WINDOW_SIZE while that buffered read is still in progress. The client then copies the full buffer into a smaller DATA callback without a runtime bounds check, which can abort the process or fail the HTTP/2 session.

    Title
    Corosync: corosync: integer overflow in check_memb_commit_token_sanity may bypass message length validation on 32-bit systems
    Summary
    An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an out-of-bounds memory access that crashes the Corosync daemon. This results in a denial of service for the affected cluster node. The overflow does not occur on 64-bit systems, where the length calculation is correctly performed in 64-bit arithmetic.

    Title
    Corosync: corosync: heap-based buffer overflow in totempg assembly buffer during fragmented message reassembly
    Summary
    A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.

This is the default when clusters are configured via \u0027pcs cluster setup\u0027, and disabling it (cipher=none/hash=none) is an explicitly unsupported configuration per upstream maintainer guidance.\n2. Restrict network access to the cluster communication ports (default 5405-5412/UDP) to trusted cluster node addresses only, using firewalld or other firewall rules.\n3.

    Vulnerability from nvd – Published: 2026-09-04 07:34 – Updated: 2026-09-04 18:15
    VLAI
    Title
    Libsoup: libsoup: heap use-after-free in libsoup http/2 client on_data_read() via goaway during body upload
    Summary
    A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution.

    Title
    Jwcrypto: jwcrypto: general json jws kid binding bypass during jwkset verification
    Summary
    A flaw was found in the jwcrypto library, which is used for implementing Javascript Object Signing and Encryption (JOSE) standards. The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users.

    CVE-2026-85150 (GCVE-0-2026-85150)

    Vulnerability from nvd – Published: 2026-09-03 10:47 – Updated: 2026-09-03 12:34
    VLAI
    Title
    Gstreamer1-plugins-base: gstreamer: null/invalid-pointer dereference in gst_rtsp_message_parse_auth_credentials() when parsing a crafted digest authorization/www-authenticate header
    Summary
    A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.

    Title
    Glib2: toctou symlink race in `g_file_create_replace_destination` fallback path
    Summary
    A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.

    Title
    389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor
    Summary
    A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host.

    Title
    389-ds-base: 389-ds-base: sasl plain authentication allows privilege escalation to directory manager via stale identity in cyrus sasl auxiliary property
    Summary
    A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority without any valid credentials. A variant using a valid low-privileged account's own successful bind instead of an anonymous one is also possible.

    Title
    389-ds-base: 389-ds-base: pre-authentication null pointer dereference via paged results and use_one_backend control in op_shared_search
    Summary
    A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.

    Title
    389-ds-base: 389-ds-base: heap buffer overflow via sasl wrapped-record length lower-bound underflow in sasl_io_start_packet()
    Summary
    A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF > 0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow.

    Title
    389-ds-base: 389-ds: anonymous ldap client can defeat selfdn aci bind-rule checks via empty bind dn
    Summary
    A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user.

    CVE-2026-79678 (GCVE-0-2026-79678)

    Vulnerability from cvelistv5 – Published: 2026-09-07 12:02 – Updated: 2026-09-07 12:02
    VLAI
    Title
    Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service
    Summary
    A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.

    Title
    Ipa: freeipa: freeipa: unauthenticated ldap client can obtain administrator credentials via the self-managed-token aci
    Summary
    A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.

    Title
    Flatpak: flatpak: toctou race condition allows symlink redirection
    Summary
    A flaw was found in Flatpak. A Time-of-check to time-of-use (TOCTOU) race condition exists in the `org.freedesktop.Flatpak.SystemHelper` component. This vulnerability occurs because a privileged `chmod` operation executes before the OSTree repository validation within the `Deploy()` function. An attacker can exploit this timing window to redirect symlinks to arbitrary files, potentially leading to unauthorized file manipulation or information disclosure.

    Title
    Libsoup: libsoup: http/2 client crash in on_data_source_read_callback when settings initial_window_size shrinks during deferred body read
    Summary
    A flaw was found in libsoup. When a client sends an HTTP/2 request body from a non-pollable input stream, the library can buffer more data than the current flow-control window later allows. A malicious HTTP/2 server can shrink SETTINGS_INITIAL_WINDOW_SIZE while that buffered read is still in progress. The client then copies the full buffer into a smaller DATA callback without a runtime bounds check, which can abort the process or fail the HTTP/2 session.

    Title
    Corosync: corosync: integer overflow in check_memb_commit_token_sanity may bypass message length validation on 32-bit systems
    Summary
    An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an out-of-bounds memory access that crashes the Corosync daemon. This results in a denial of service for the affected cluster node. The overflow does not occur on 64-bit systems, where the length calculation is correctly performed in 64-bit arithmetic.

    Title
    Corosync: corosync: heap-based buffer overflow in totempg assembly buffer during fragmented message reassembly
    Summary
    A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.

    Title
    Libsoup: libsoup: heap use-after-free in libsoup http/2 client on_data_read() via goaway during body upload
    Summary
    A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution.

    CVE-2026-84185 (GCVE-0-2026-84185)

    Vulnerability from cvelistv5 – Published: 2026-09-03 20:46 – Updated: 2026-09-04 18:57

    Title
    Jwcrypto: jwcrypto: general json jws kid binding bypass during jwkset verification
    Summary
    A flaw was found in the jwcrypto library, which is used for implementing Javascript Object Signing and Encryption (JOSE) standards. The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users.

The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users."
