Package : libapache-mod-security
Vulnerability : modsecurity bypass
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-2751
Debian Bug : #678529
Qualys Vulnerability & Malware Research Labs discovered a vulnerability in
ModSecurity, a security module for the Apache webserver. In situations where
both 'Content:Disposition: attachment' and 'Content-Type: multipart' were
present in HTTP headers, the vulernability could allow an attacker to bypass
policy and execute cross-site script (XSS) attacks through properly crafted
HTML documents.
For the stable distribution (squeeze), this problem has been fixed in
version 2.5.12-1+squeeze1.
For the testing distribution (wheezy), this problem has been fixed in
version 2.6.6-1.
For the unstable distribution (sid), this problem has been fixed in
version 2.6.6-1.
In testing and unstable distribution, the source package has been renamed to
modsecurity-apache.
We recommend that you upgrade your libapache-mod-security packages.
