Debian DSA-1461-1 : libxml2 - missing input validation

medium Nessus Plugin ID 29938

Synopsis

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

Description

Brad Fitzpatrick discovered that the UTF-8 decoding functions of libxml2, the GNOME XML library, validate UTF-8 correctness insufficiently, which may lead to denial of service by forcing libxml2 into an infinite loop.

Solution

Upgrade the libxml2 packages.

For the old stable distribution (sarge), this problem has been fixed in version 2.6.16-7sarge1.

For the stable distribution (etch), this problem has been fixed in version 2.6.27.dfsg-2.
