CVE-2015-2331 is an integer overflow vulnerability in the libzip library (versions 0.11.2 and earlier), specifically within the _zip_cdir_new function. This flaw affects products utilizing libzip, including PHP versions before 5.4.39, 5.5.23, and 5.6.7, as well as Debian, Fedora, NIH, and OpenSUSE. With a CVSS score of 7.5, this vulnerability is considered highly severe, allowing remote attackers to trigger a denial of service (application crash) or potentially execute arbitrary code via a specially crafted ZIP archive containing numerous entries, leading to a heap-based buffer overflow. While the FAUCET Risk Score is 96/100 and its EPSS score is higher than 96% of all CVEs, there is no evidence of active exploitation, no known exploit code in Metasploit or ExploitDB, and minimal community discussion or media coverage.
