CVE-2005-4591

High
Published: Translated: NVD NIST

Summary

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, a heap-based buffer overflow exists. A remote attacker can exploit this by sending invalid input sequences, leading to heap corruption and potentially causing a denial of service or arbitrary code execution.

Risk Assessment

The risk for the organization includes the possibility of remote code execution by an attacker on a mail server using bogofilter, which could lead to system compromise and data leakage.

Recommendation

Immediately upgrade bogofilter to version 1.0.0 or later, which includes a fix for this vulnerability.
