CVE-2026-33996 (GCVE-0-2026-33996)

Vulnerability from cvelistv5 – Published: 2026-03-27 22:21 – Updated: 2026-03-31 18:53

Title
LibJWT has NULL/bounds validation in JWK octet and RSA PSS parsing
Summary
LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the code expected a string. This was fixed in v3.3.0. A workaround is available. Users importing keys through a JWK file should not do so from untrusted sources. Use the `jwk2key` tool to check for validity of a JWK file. Likewise, if possible, do not use JWK files with RSA-PSS keys.

Title
iccDEV: UB in CIccCombinedConnectionConditions::CIccCombinedConnectionConditions()
Summary
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) via a null-pointer member call in CIccCombinedConnectionConditions::CIccCombinedConnectionConditions() (reported by UBSan as “member call on null pointer of type CIccTagSpectralViewingConditions”). The issue is reachable when running iccApplyNamedCmm with -PCC using a malformed .icc profile. This issue has been patched in version 2.3.1.6.

iccDEV: NPD in CIccTagLut16::Write()
Summary
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a null-pointer dereference (NPD) in CIccTagLut16::Write() can be triggered when processing a crafted ICC profile (embedded in a TIFF and extracted during iccTiffDump). This issue has been patched in version 2.3.1.6.

Mitigation ID: MIT-56

Phase: Implementation

Description:

  • For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation

Phase: Requirements

Description:

  • Select a programming language that is not susceptible to these issues.
Mitigation

Phase: Implementation

Description:

  • Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation

Phase: Architecture and Design

Description:

  • Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation

Phase: Implementation

Description:

  • Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
