CVE-2012-1438

Estado: ModificadaMedia (4.3)—

The Microsoft Office file parser in Comodo Antivirus 7425 and Sophos Anti-Virus 4.61.0 allows remote attackers to bypass malware detection via an Office file with a ustar character sequence at a certain location. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different Office parser implementations.
