Debian Security Advisory DSA-2327-1 [email protected]
http://www.debian.org/security/ Nico Golde
Oct 24th, 2011 http://www.debian.org/security/faq
Package : libfcgi-perl
Vulnerability : authentication bypass
Problem type : remote
Debian-specific: no
Debian bug : 607479
CVE IDs : CVE-2011-2766
Ferdinand Smit discovered that libfcgi-perl, a Perl module for writing
FastCGI applications, is incorrectly restoring environment variables of
a prior request in subsequent requests. In some cases this may lead
to authentication bypasses or worse.
The oldstable distribution (lenny) is not affected by this problem.
For the stable distribution (squeeze), this problem has been fixed in
version 0.71-1+squeeze1.
For the testing distribution (wheezy), this problem has been fixed in
version 0.73-2.
For the unstable distribution (sid), this problem has been fixed in
version 0.73-2.
We recommend that you upgrade your libfcgi-perl packages.
