Summary
mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. When mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc` wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use when this option is enabled.

Connect Provider. When mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc` wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use when this option is enabled.", title: "CVE description", }, ], product_status: { recommended: [ "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", ], }, references: [ { category: "external", summary: "CVE-2021-32785", url: "https://www.suse.com/security/cve/CVE-2021-32785", }, { category: "external", summary: "SUSE Bug 1188638 for CVE-2021-32785", url: "https://bugzilla.suse.com/1188638", }, ], remediations: [ { category: "vendor_fix", details: "To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n", product_ids: [ "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", ], }, ], scores: [ { cvss_v3: { baseScore: 5.3, baseSeverity: "MEDIUM", vectorString: "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", version: "3.1", }, products: [ "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP2:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.aarch64", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.ppc64le", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.s390x", "SUSE Linux Enterprise Module for Server Applications 15 SP3:apache2-mod_auth_openidc-2.3.8-3.15.1.x86_64", ], }, ], threats: [ { category: "impact", date: "2021-09-13T07:17:22Z", details: "moderate", }, ], title: "CVE-2021-32785", }, { cve: "CVE-2021-32786", ids: [ { system_name: "SUSE CVE Page", text: "https://www.suse.com/security/cve/CVE-2021-32786", }, ], notes: [ { category: "general", text: "mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider.

Summary
mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. When mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc` wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use when this option is enabled.
