Name of the Vulnerable Software and Affected Versions GnuTLS versions prior to 3.3.26 GnuTLS versions 3.5.x prior to 3.5.8

Description The issue is related to a stack-based buffer overflow in the cdk pk get keyid function, which can be exploited by remote attackers using a crafted OpenPGP certificate. This may allow attackers to have an unspecified impact on the system.

Recommendations For GnuTLS versions prior to 3.3.26, update to version 3.3.26 or later. For GnuTLS versions 3.5.x prior to 3.5.8, update to version 3.5.8 or later. As a temporary workaround, consider restricting the use of the cdk pk get keyid function until a patch is available.
