DescriptionNVD

A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.

AnalysisAI

Memory corruption via an off-by-one error in GnuTLS PKCS#12 bag element handling exposes any application using GnuTLS to remote unauthenticated denial of service - and potentially unspecified further impact - when a crafted PKCS#12 structure is parsed. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication, no user interaction, and no elevated complexity, making internet-exposed services that parse client-supplied PKCS#12 inputs the primary risk surface. …
