Vulnerability  : use-after-free
Problem type   : local (remote)
Debian-specific: no
CVE Id(s)      : CVE-2010-2547
Debian Bug     : 590122

It was discovered that GnuPG 2 uses a freed pointer when verify a
signature or importing a certificate with many Subject Alternate Names,
potentially leading to arbitrary code execution.

For the stable distribution (lenny), this problem has been fixed in
version 2.0.9-3.1+lenny1.

For the unstable distribution (sid), this problem has been fixed in
version  2.0.14-2.

GnuPG 1 (in the gnupg package) is not affected by this problem.

We recommend that you upgrade your gnupg2 packages.
