Package        : gnupg2
Vulnerability  : integer overflow
Problem type   : local (remote)
Debian-specific: no
CVE ID         : CVE-2006-3082

Evgeny Legerov discovered that gnupg, the GNU privacy guard, a free
PGP replacement contains an integer overflow that can cause a
segmentation fault and possibly overwrite memory via a large user ID
strings.

For the stable distribution (sarge) this problem has been fixed in
version 1.4.1-1.sarge4 of GnuPG and in version 1.9.15-6sarge1 of GnuPG2.

For the unstable distribution (sid) this problem has been fixed in
version 1.4.3-2 of GnuPG, a fix for GnuPG2 is pending.

We recommend that you upgrade your gnupg package.
