EulerOS 2.0 SP2 : libxslt (EulerOS-SA-2019-2519)

critical Nessus Plugin ID 131672
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libxslt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- This C library allows to transform XML files into other XML files (or HTML, text, ...) using the standard XSLT stylesheet transformation mechanism. To use it you need to have a version of libxml2 i1/4z= 2.6.27 installed. The xsltproc command is a command line interface to the XSLT engine.Security Fix(es):In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.(CVE-2019-18197)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.(CVE-2015-7995)numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles namespace nodes, which allows remote attackers to cause a denial of service (out-of-bounds heap memory access) or possibly have unspecified other impact via a crafted document.(CVE-2016-1683)numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles the i format token for xsl:number data, which allows remote attackers to cause a denial of service (integer overflow or resource consumption) or possibly have unspecified other impact via a crafted document.(CVE-2016-1684)libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors, a different vulnerability than CVE-2016-4608, CVE-2016-4609, CVE-2016-4610, and CVE-2016-4612.(CVE-2016-4607)libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors, a different vulnerability than CVE-2016-4607, CVE-2016-4609, CVE-2016-4610, and CVE-2016-4612.(CVE-2016-4608)libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors, a different vulnerability than CVE-2016-4607, CVE-2016-4608, CVE-2016-4610, and CVE-2016-4612.(CVE-2016-4609)libxslt in Apple iOS before 9.3.3, OS X before 10.11.6, iTunes before 12.4.2 on Windows, iCloud before 5.2.1 on Windows, tvOS before 9.2.2, and watchOS before 2.2.2 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors, a different vulnerability than CVE-2016-4607, CVE-2016-4608, CVE-2016-4609, and CVE-2016-4612.(CVE-2016-4610)** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2016-1683.
Reason: This candidate is a reservation duplicate of CVE-2016-1683. Notes: All CVE users should reference CVE-2016-1683 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2016-4612)In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a 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-2019-13117)In numbers.c in libxslt 1.1.33, 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.(CVE-2019-13118)

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

Solution

Update the affected libxslt packages.
