Debian Security Advisory DSA-2641-1 security@debian.org

March 09, 2013 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : perl
Vulnerability : rehashing flaw
Problem type : remote
Debian-specific: no
CVE ID : CVE-2013-1667
Debian Bug : 702296
Yves Orton discovered a flaw in the rehashing code of Perl. This flaw
could be exploited to carry out a denial of service attack against code
that uses arbitrary user input as hash keys. Specifically an attacker
could create a set of keys of a hash causing a denial of service via
memory exhaustion.
For the stable distribution (squeeze), this problem has been fixed in
version 5.10.1-17squeeze6.
For the testing distribution (wheezy), and the unstable distribution
(sid), this problem has been fixed in version 5.14.2-19.
We recommend that you upgrade your perl packages.
