Published: 2010-03-26 · updated 2026-06-16
Weakness: CWE-119

Description

The gnutls_x509_crt_get_serial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1_read_value with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list (CRL) check and cause a stack-based buffer overflow via a crafted X.509 certificate, related to extraction of a serial number.

Affected products

[UNKNOWN] gnutls: through 1.2.0; 1.0.16, 1.0.17, 1.0.18, 1.0.19, 1.0.20, 1.0.21 (+15)
