CVE-2009-1415

Publication date 30 April 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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 pointer or (2) double free.
