CVE-2007-3508

18
FAUCET Score

CVE-2007-3508 describes an integer overflow in the process_envvars function within glibc, specifically affecting versions before 2.5-rc4, which could allow local users to execute arbitrary code through a large LD_HWCAP_MASK environment variable. This vulnerability carries a CVSS score of 7.2, indicating high severity with local access and low complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. Despite the high CVSS score, glibc maintainers doubt its exploitability for code execution, and there is no evidence of active exploitation, public exploit code, or significant community discussion or media coverage.
