CVE-2005-4591: Heap-based buffer overflow in bogofilter 0.96.2, 0.95.2, 0.94.14, 0.94.12, and other versions from 0.93.5 t...

Heap-based buffer overflow in bogofilter 0.96.2, 0.95.2, 0.94.14, 0.94.12, and other versions from 0.93.5 to 0.96.2, when using Unicode databases, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via "invalid input sequences" that lead to heap corruption when bogofilter or bogolexer converts character sets.

Security readout for executives and security teams

CVE-2005-4591 affects old bogofilter spam-filtering software. Specially malformed character data can corrupt heap memory while bogofilter converts character sets. The documented impact is service crash, with possible arbitrary code execution. Business urgency depends on whether any legacy mail filtering still uses affected versions and Unicode databases. Exposure is likely limited to legacy systems that still run affected bogofilter versions in mail-processing paths, especially with Unicode databases enabled. Modern supported distributions are unlikely to carry these exact versions, but archived appliances or custom mail gateways may. Treat as a legacy exposure check, not an emergency unless vulnerable bogofilter is still in production mail flow. If found on internet-facing mail processing, prioritize remediation because the impact may go beyond crashes. Mitigation focus: Inventory all mail gateways and hosts for bogofilter installations.; Check Ubuntu, SUSE, or bogofilter advisories for fixed package guidance.; Upgrade or retire versions 0.93.5 through 0.96.2 where found..
