Source: libxslt
Version: 1.1.28-2
Severity: grave
Tags: security upstream patch

Hi,

the following vulnerability was published for libxslt.

CVE-2016-4738[0]:
| libxslt in Apple iOS before 10, OS X before 10.12, tvOS before 10, and
| watchOS before 3 allows remote attackers to execute arbitrary code or
| cause a denial of service (memory corruption) via a crafted web site.

Unfortunately as for many libxml2 issues, the above is not very
specific and there is upstream bug referenced. But the fix is
mentioned as [1].

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
