CVE-2003-0390

21
FAUCET Score

CVE-2003-0390 describes multiple buffer overflows in versions 3.18 and earlier of the Options Parsing Tool (OPT) shared library, specifically when used in setuid programs. This vulnerability allows local users to execute arbitrary code by providing excessively long command line options that are processed by macros like opt_warn_2 and functions such as opt_atoi. With a CVSS score of 4.6, it is considered a local attack with low complexity, potentially leading to partial confidentiality, integrity, and availability impacts. While there is no evidence of active exploitation in the wild or Metasploit/Nuclei modules, two ExploitDB entries exist, indicating proof-of-concept code for error logging buffer overflows. Community discussion and media coverage for this CVE are minimal.
