Bug 831573 (GNUTLS-SA-2022-01-17) – <net-libs/gnutls-3.7.3: Memory corruption in gnutls_x509_trust_list_verify_crt2()

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Sam James 2022-01-20 11:24:57 UTC]

"When a single trust list object is shared among multiple threads, calls to gnutls_x509_trust_list_verify_crt2() was able to corrupt temporary memory where internal copy of an issuer certificate is stored. The code path is only taken when a PKCS#11 based trust store is enabled and the issuer certificate is already stored as trusted. The issue was reported in the issue tracker as #1277.
Recommendation: To address the issue found upgrade to GnuTLS 3.7.3 or later versions."

See https://gitlab.com/gnutls/gnutls/-/issues/1277.
