CVE Descriptions

Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Author : Chris Evans
EDB Verified : Yes

source: https://www.securityfocus.com/bid/48056/info The 'libxml2' library is prone to multiple memory-corruption vulnerabilities, including one that can trigger a heap-based buffer-overflow error and an integer-overflow condition. An attacker can exploit these issues by enticing an unsuspecting user into opening a specially crafted XML file that contains a malicious XPath. A successful attack can allow attacker-supplied code to run in the context of the application using the vulnerable library or can cause a denial-of-service condition. //@*/preceding::node()/ancestor::node()/ancestor::foo['foo']
