More information:

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.

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

For the testing distribution (stretch), this problem has been fixed in version 1.1.29-2.

For the unstable distribution (sid), this problem has been fixed in version 1.1.29-2.

We recommend that you upgrade your libxslt packages.
