Debian DSA-3709-1 : libxslt - security update

high Nessus Plugin ID 94645

Language:

Synopsis

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

Description

Nick Wellnhofer discovered that the xsltFormatNumberConversion function in libxslt, an XSLT processing runtime library, does not properly check for a zero byte terminating the pattern string. This flaw can be exploited to leak a couple of bytes after the buffer that holds the pattern string.

Solution

Upgrade the libxslt packages.

For the stable distribution (jessie), this problem has been fixed in version 1.1.28-2+deb8u2.
