Package        : libimager-perl
Vulnerability  : buffer overflow
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2007-2459
Debian Bug     : 421582


It was discovered that libimager-perl, a Perl extension for Generating 24
bit images, did not correctly handle 8-bit per-pixel compressed images,
which could allow the execution of arbitrary code.

For the stable distribution, this problem has been fixed in version
0.50-1etch1.

We recommend that you upgrade your libimager-perl package.
