CVE-2011-1071

34
FAUCET Score

CVE-2011-1071 describes a stack extension vulnerability in GNU C Library (glibc) before version 2.12.2 and Embedded GLIBC (EGLIBC). This flaw allows context-dependent attackers to execute arbitrary code or cause a denial of service through excessive memory consumption by providing a long UTF8 string to an fnmatch call. Rated with a CVSS score of 5.1, this vulnerability has a network attack vector and high attack complexity, potentially leading to partial compromise of confidentiality, integrity, and availability. While not actively exploited in the wild and not listed in CISA's KEV catalog, public exploit code exists, specifically EDB-17120, though there is minimal community discussion or media coverage surrounding this CVE.
