Debian Security Advisory DSA-1477-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
January 27, 2008 http://www.debian.org/security/faq
- - ------------------------------------------------------------------------
Package : yarssr
Vulnerability : missing input sanitising
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2007-5837
Duncan Gilmore discovered that yarssr, an RSS aggregator and reader,
performs insufficient input sanitising, which could result in the
execution of arbitrary shell commands if a malformed feed is read.
For the stable distribution (etch), this problem has been fixed in
version 0.2.2-1etch1.
Due to a technical limitation of the archive management scripts, the
fix for the old stable distribution (sarge) needs to be postponed
by a few days.
We recommend that you upgrade your yarssr packages.
