This update for libxslt fixes the following security 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) This update was     imported from the SUSE:SLE-12:Update update project.

Holger Fuhrmannek discovered an integer overflow in the xsltAddTextString() function in Libxslt. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash) or possible execute arbitrary code.
(CVE-2017-5029)

Nicolas Gregoire discovered that Libxslt mishandled namespace nodes.
An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash) or possibly execute arbtrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1683)

Sebastian Apelt discovered that a use-after-error existed in the xsltDocumentFunctionLoadDocument() function in Libxslt. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash) or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1841)

It was discovered that a type confusion error existed in the xsltStylePreCompute() function in Libxslt. An attacker could use this to craft a malicious XML file that, when opened, caused a denial of service (application crash). This issue only affected Ubuntu 14.04 LTS and Ubuntu 12.04 LTS. (CVE-2015-7995)

Nicolas Gregoire discovered the Libxslt mishandled the 'i' and 'a' format tokens for xsl:number data. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash). This issue only affected Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-1684)

It was discovered that the xsltFormatNumberConversion() function in Libxslt did not properly handle empty decimal separators. An attacker could use this to craft a malicious document that, when opened, could cause a denial of service (application crash). This issue only affected Ubuntu 16.10, Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS. (CVE-2016-4738).

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

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.

A heap overread bug was found in libxslt, which can cause arbitrary code execution or denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.26-14.1+deb7u2.

We recommend that you upgrade your libxslt packages.
