gnutls: Stack-based Buffer Overflow in gnutls_pkcs11_token_init() Function

A flaw was found in the GnuTLS library, specifically in the gnutlspkcs11tokeninit function that handles PKCS11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the applicatio...

FreeBSD : GnuTLS -- Stack write buffer overflow (b6835edf-c6c8-11f0-8471-74563cf9e4e9)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the b6835edf-c6c8-11f0-8471-74563cf9e4e9 advisory. GnuTLS reports: When a PKCS11 token is initialized with gnutlspkcs11tokeninit function and it is passed...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow via the gnutlspkcs11tokeninit function. An attacker can cause a crash or potentially execute arbitrary code by supplying a PKCS11 token with a label longer than 32 characters, leading to writing past the end ...
