gnutls vulnerability

About this tag
The gnutls vulnerability tag covers discussions about security flaws in the GnuTLS library, including CVE-2026-42010 (a NUL byte authentication bypass in RSA-PSK), CVE-2024-28834 (a Minerva-style side-channel weakness), and CVE-2024-0553. These vulnerabilities affect systems that rely on GnuTLS, such as Azure Linux and other Microsoft products that include the library. Topics include mitigation strategies, artifact discovery, and the broader implications for identity security at the byte level. The tag is relevant for IT professionals managing cross-platform environments where GnuTLS is used.

  1. CVE-2026-42015 GnuTLS PKCS#12 Off-by-One: Patch Availability Risk in Hybrid Windows

    Microsoft has listed CVE-2026-42015 in its Security Update Guide as a GnuTLS memory-corruption flaw, disclosed in spring 2026, involving an off-by-one error in PKCS#12 bag handling that can let a remote unauthenticated attacker trigger a limited denial-of-service condition. The bug is not a...
