Debian Linux Security Advisory 2801-1 - Jonathan Dolle reported a design error in HTTP::Body, a Perl module for processing data from HTTP POST requests. The HTTP body multipart parser creates temporary files which preserve the suffix of the uploaded file. An attacker able to upload files to a service that uses HTTP::Body::Multipart could potentially execute commands on the server if these temporary filenames are used in subsequent commands without further checks.

Package : libhttp-body-perl
Vulnerability : design error
Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2013-4407
Debian Bug : 721634

Jonathan Dolle reported a design error in HTTP::Body, a Perl module for
processing data from HTTP POST requests. The HTTP body multipart parser
creates temporary files which preserve the suffix of the uploaded file.
An attacker able to upload files to a service that uses
HTTP::Body::Multipart could potentially execute commands on the server
if these temporary filenames are used in subsequent commands without
further checks.

This update restricts the possible suffixes used for the created
temporary files.

The oldstable distribution (squeeze) is not affected by this problem.

For the stable distribution (wheezy), this problem has been fixed in
version 1.11-1+deb7u1.

For the testing distribution (jessie), this problem has been fixed in
version 1.17-2.

For the unstable distribution (sid), this problem has been fixed in
version 1.17-2.

We recommend that you upgrade your libhttp-body-perl packages.
