Debian DLA-1860-1 : libxslt security update

critical Nessus Plugin ID 126926

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were found in libxslt the XSLT 1.0 processing library.

CVE-2016-4610

Invalid memory access leading to DoS at exsltDynMapFunction. libxslt allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

CVE-2016-4609

Out-of-bounds read at xmlGetLineNoInternal() libxslt allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

CVE-2019-13117

An xsl:number with certain format strings could lead to an uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character.

CVE-2019-13118

A type holding grouping characters of an xsl:number instruction was too narrow and an invalid character/length combination could be passed to xsltNumberFormatDecimal, leading to a read of uninitialized stack data.

For Debian 8 'Jessie', these problems have been fixed in version 1.1.28-2+deb8u5.

We recommend that you upgrade your libxslt packages.

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

Solution

Upgrade the affected packages.
