TITLE

libxslt of preproc.c of xsltStylePreCompute Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

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. Supplementary information : CWE Vulnerability type by CWE-843:Access of Resource Using Incompatible Type ( Mixing of molds ) Has been identified. http://cwe.mitre.org/data/definitions/843.htmlCrafted by attackers XML Through the file Service operation interruption (DoS) There is a possibility of being put into a state. libxslt is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause denial-of-service condition. libxslt 1.1.28 is vulnerable; other versions may also be affected. libxslt is an XSLT (XML language for defining XML transformations) C library developed for the GNOME project. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2016-03-21-2 watchOS 2.2 watchOS 2.2 is now available and addresses the following: Disk Images Available for: Apple Watch Sport, Apple Watch, Apple Watch Edition, and Apple Watch Hermes Impact: An application may be able to execute arbitrary code with kernel privileges Description: A memory corruption issue existed in the parsing of disk images.

Software Description: - libxslt: XSLT processing library Details: 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.
