An issue was discovered in Prevx v3.0.5.220 allowing attackers to cause a denial of service via sending IOCTL code 0x22E044 to the pxscan.sys driver. Any processes listed under registry key HKEYLOCALMACHINE\System\CurrentControlSet\Services\pxscan\Files will be terminated.

DISPUTED Race condition in Prevx 3.0.5.143 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute.

The ELF file parser in eSafe 7.0.17.0, Prevx 3.0, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified abiversion field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations.

The Microsoft EXE file parser in eSafe 7.0.17.0 and Prevx 3.0 allows remote attackers to bypass malware detection via an EXE file with a modified value in any of several e fields. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different EXE parser implementations.
