Debian Security Advisory DSA-2991-1 security@debian.org
http://www.debian.org/security/ Salvatore Bonaccorso
July 27, 2014 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : modsecurity-apache
CVE ID : CVE-2013-5705
Martin Holst Swende discovered a flaw in the way chunked requests are
handled in ModSecurity, an Apache module whose purpose is to tighten the
Web application security. A remote attacker could use this flaw to
bypass intended mod_security restrictions by using chunked transfer
coding with a capitalized Chunked value in the Transfer-Encoding HTTP
header, allowing to send requests containing content that should have
been removed by mod_security.
For the stable distribution (wheezy), this problem has been fixed in
version 2.6.6-6+deb7u2.
For the testing distribution (jessie), this problem has been fixed in
version 2.7.7-1.
For the unstable distribution (sid), this problem has been fixed in
version 2.7.7-1.
We recommend that you upgrade your modsecurity-apache packages.
