21
FAUCET Score

CVE-2001-0653 describes a vulnerability in Sendmail versions 8.10.0 through 8.11.5, and 8.12.0 beta, where a local user can manipulate process memory and potentially gain privileges. This occurs by providing a large value to the 'category' part of the debugger (-d) command-line arguments, which is then misinterpreted as a negative number. The vulnerability has a CVSS score of 4.6 (MEDIUM), indicating a local attack vector with low complexity, potentially leading to partial confidentiality, integrity, and availability impacts. While not listed on the KEV catalog or Hot List, multiple exploit proofs-of-concept are available on ExploitDB, demonstrating arbitrary code execution. There is no evidence of active exploitation, and it has received minimal community discussion or media coverage.
