Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for libxslt fixes the following issues :

- CVE-2017-5029: The xsltAddTextString function in transform.c lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page (bsc#1035905).

- CVE-2016-4738: Fix heap overread in xsltFormatNumberConversion: An empty decimal-separator could cause a heap overread. This can be exploited to leak a couple of bytes after the buffer that holds the pattern string (bsc#1005591).

- CVE-2015-9019: Properly initialize random generator (bsc#934119).

- CVE-2015-7995: Vulnerability in function xsltStylePreCompute' in preproc.c could cause a type confusion leading to DoS. (bsc#952474)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
