Synopsis
The remote AIX host has a version of libxml2 installed that is affected by multiple vulnerabilities.Description
The remote AIX host has a version of libxml2 installed that is affected by the following vulnerabilities :- A heap-based buffer overflow condition exists in the xmlParseEntityDecl() and xmlParseConditionalSections() functions within file parser.c due to a failure to properly stop parsing invalid input. An unauthenticated, remote attacker can exploit this, via specially crafted XML data, to cause a denial of service condition or potentially disclose sensitive memory contents.
(CVE-2015-7941)
- A heap-based buffer overflow condition exists in the xmlParseConditionalSections() function within file parser.c due to not properly skipping intermediary entities. An unauthenticated, remote attacker can exploit this, via specially crafted XML data, to cause a denial of service condition. (CVE-2015-7942)
- A buffer overflow condition exists in the xmlNextChar() function due to improper bounds checking. A local attacker can exploit this, via a malformed XML file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-8241)
