USN-7281-1: GnuTLS vulnerability

Bing Shi discovered that GnuTLS incorrectly handled decoding certain DER-encoded certificates. A remote attacker could possibly use this issue to cause GnuTLS to consume resources, leading to a denial of service...

ALPINE-CVE-2024-12243

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially...

SUSE CVE-2009-1415

lib/pk-libgcrypt.c in libgnutls in GnuTLS before 2.6.6 does not properly handle invalid DSA signatures, which allows remote attackers to cause a denial of service application crash and possibly have unspecified other impact via a malformed DSA key that triggers a 1 free of an uninitialized pointe...

SUSE CVE-2009-1417

gnutls-cli in GnuTLS before 2.6.6 does not verify the activation and expiration times of X.509 certificates, which allows remote attackers to successfully present a certificate that is 1 not yet valid or 2 no longer valid, related to lack of time checks in the gnutlsx509verifycertificate function...
