Synopsis

The remote Debian host is missing a security-related update.

Description

Tilmann Haak from xing.com discovered that XML::LibXML, a Perl interface to the libxml2 library, did not respect the expand_entities parameter to disable processing of external entities in some circumstances. This may allow attackers to gain read access to otherwise protected resources, depending on how the library is used.

Solution

Upgrade the libxml-libxml-perl packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 2.0001+dfsg-1+deb7u1.

For the stable distribution (jessie), this problem has been fixed in version 2.0116+dfsg-1+deb8u1.
