Apple Mac OS X BOMArchiveHelper buffer overflow

macosx-archivehelper-bo (25945) The risk level is classified as HighHigh Risk


Apple Mac OS X is vulnerable to a heap-based buffer overflow in the BOMArchiveHelper application, which is the default file archive application in Mac OS X. By creating a malicious ZIP archive, and then persuading a victim to open the malicious archive, a remote attacker could overflow a buffer in the BOMStackPop() function and cause the application to crash or possibly execute arbitrary code on the system. An attacker could exploit this vulnerability by hosting the malicious archive on a Web site or sending it to a victim as an email attachment.
