36
FAUCET Score

CVE-2009-1391 is an off-by-one error in the inflate function of the Compress::Raw::Zlib Perl module, affecting products like AMaViS and SpamAssassin. This vulnerability allows remote attackers to cause a denial of service (hang or crash) via a crafted zlib compressed stream, potentially leading to a heap-based buffer overflow. With a CVSS score of 6.8, it is considered a medium-severity vulnerability, requiring medium attack complexity but potentially leading to partial confidentiality, integrity, and availability impacts. The vulnerability was exploited in the wild by Trojan.Downloader-71014 in June 2009, and an exploit for remote code execution is available on ExploitDB, despite a lack of broader community discussion or media coverage.
