CVE-2007-2026: The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of servic...

Security readout for executives and security teams

This is a denial-of-service issue from 2007 affecting GNU regular expression handling in file 4.20. A crafted document with many line feeds could make vulnerable scanning logic consume excessive CPU, potentially slowing mail or content-processing systems. The source bundle does not provide CVSS scoring or confirmed active exploitation. Exposure is most plausible where legacy systems still run vulnerable file 4.20 behavior in automated document, mail, or antivirus scanning workflows. Current exposure should be verified through package inventories and the cited vendor advisories because the bundle lists affected products incompletely. Treat as a legacy availability risk, not a broad emergency. Prioritize if vulnerable scanning components sit in mail gateways or other high-volume ingestion paths where CPU exhaustion could disrupt business workflows. Mitigation focus: Check Gentoo, Mandriva, rPath, and AMaViS advisories for applicable vendor updates.; Identify and retire systems still using file 4.20 or vulnerable downstream packages.; Prioritize update validation on mail gateways and automated content scanners..
