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)

The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check if the parent node is an element, which allows attackers to cause a denial of service via a crafted XML file, related to a "type confusion" issue.

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)
