Title
Envoy’s TLS certificate matcher for `match_typed_subject_alt_names` may incorrectly treat certificates containing an embedded null byte
Summary
Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier, Envoy’s mTLS certificate matcher for match_typed_subject_alt_names may incorrectly treat certificates containing an embedded null byte (\0) inside an OTHERNAME SAN value as valid matches.

CVE-2026-2239 (GCVE-0-2026-2239)

Title
Gimp: gimp: application crash (dos) via crafted psd file due to heap-buffer-overflow
Summary
A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service.

CVE-2026-23749 (GCVE-0-2026-23749)

Title
Golioth Firmware SDK < 0.22.0 Blockwise Transfer Path Out-of-Bounds Read
Summary
Golioth Firmware SDK version 0.19.1 prior to 0.22.0, fixed in commit 0e788217, contain an out-of-bounds read due to improper null termination of a blockwise transfer path. blockwise_transfer_init() accepts a path whose length equals CONFIG_GOLIOTH_COAP_MAX_PATH_LEN and copies it using strncpy() without guaranteeing a trailing NUL byte, leaving ctx->path unterminated. A later strlen() on this buffer (in golioth_coap_client_get_internal()) can read past the end of the allocation, resulting in a crash/denial of service. The input is application-controlled (not network by default).

CVE-2026-24852 (GCVE-0-2026-24852)

Vulnerability from cvelistv5 – Published: 2026-01-28 00:27 – Updated: 2026-01-28 14:51

Title
iccDEV has a heap-buffer-overflow in icXmlParseTextString()
Summary
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, a heap buffer over-read when the strlen() function attempts to read a non-null-terminated buffer potentially leaking heap memory contents and causing application termination. This vulnerability affects users of the iccDEV library who process ICC color profiles. ICC Profile Injection vulnerabilities arise when user-controllable input is incorporated into ICC profile data or other structured binary blobs in an unsafe manner. Version 2.3.1.2 contains a fix for the issue. No known workarounds are available.

Title
iccDEV has HBO in CIccTagTextDescription::Release()
Summary
iccDEV provides a set of libraries and tools for working with ICC color management profiles. In versions up to and including 2.3.1.4, heap-buffer-overflow read occurs during CIccTagTextDescription::Release() when strlen() reads past a heap buffer while parsing ICC profile XML text description tags, causing a crash. Commit 29d088840b962a7cdd35993dfabc2cb35a049847 fixes the issue. No known workarounds are available.

CVE-2026-32837 (GCVE-0-2026-32837)

Vulnerability from cvelistv5 – Published: 2026-03-17 19:10 – Updated: 2026-04-27 15:38

Title
mackron / miniaudio Out-of-Bounds Read in BEXT Coding History Parsing
Summary
miniaudio version 0.11.25 and earlier (fixed in commits 1df46ae and 1df46ae) contain a heap out-of-bounds read vulnerability in the WAV BEXT metadata parser that allows attackers to trigger memory access violations by processing crafted WAV files. Attackers can exploit improper null-termination handling in the coding history field to cause out-of-bounds reads past the allocated metadata pool, resulting in application crashes or denial of service.

CVE-2026-33948 (GCVE-0-2026-33948)

Title
jq: Embedded-NUL Truncation in CLI JSON Input Path Causes Prefix-Only Validation of Malformed Input
Summary
jq is a command-line JSON processor. Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen() to determine buffer length instead of the actual byte count from fgets(), causing it to truncate input at the first NUL byte and parse only the preceding prefix. This enables an attacker to craft input with a benign JSON prefix before a NUL byte followed by malicious trailing data, where jq validates only the prefix as valid JSON while silently discarding the suffix. Workflows relying on jq to validate untrusted JSON before forwarding it to downstream consumers are susceptible to parser differential attacks, as those consumers may process the full input including the malicious trailing bytes. This issue has been patched by commit 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b.

CVE-2026-34462 (GCVE-0-2026-34462)

Title
Sandboxie-Plus ProcessServer boxname stack buffer overflows via unterminated wide string copy
Summary
Sandboxie-Plus is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, several ProcessServer handlers (KillAllHandler, SuspendAllHandler, and RunSandboxedHandler) copy a WCHAR boxname[34] field from request structures into WCHAR[40] stack buffers using wcscpy without verifying null termination. Because the service pipe accepts variable-length packets larger than the request structure, an attacker can fill the boxname field with non-zero data and append additional controlled wide characters after the structure. wcscpy then reads past the fixed field and overflows the destination stack buffer. The service pipe is created with a NULL DACL, allowing any local process to connect, and the unsafe copy occurs before authorization checks. This can lead to a crash of the SbieSvc service or potential code execution as SYSTEM. This issue has been fixed in version 1.17.3.

Mitigation

Phase: Requirements

Description:

  • Use a language that is not susceptible to these issues. However, be careful of null byte interaction errors (CWE-626) with lower-level constructs that may be written in a language that is susceptible.
Mitigation

Phase: Implementation

Description:

  • Ensure that all string functions used are understood fully as to how they append null characters. Also, be wary of off-by-one errors when appending nulls to the end of strings.
Mitigation

Phase: Implementation

Description:

  • If performance constraints permit, special code can be added that validates null-termination of string buffers, this is a rather naive and error-prone solution.
Mitigation

Phase: Implementation

Description:

  • Switch to bounded string manipulation functions. Inspect buffer lengths involved in the buffer overrun trace reported with the defect.
Mitigation

Phase: Implementation

Description:

  • Add code that fills buffers with nulls (however, the length of buffers still needs to be inspected, to ensure that the non null-terminated string is not written at the physical end of the buffer).
