Dr.Web Firewall 12.5.2.4160 on Windows incorrectly restricts applications signed by Dr.Web. A DLL for a custom payload within a legitimate binary (e.g., frwl_svc.exe) bypasses firewall filters.

Dr.Web Security Space versions 11 and 12 allow elevation of privilege for local users without administrative privileges to NT AUTHORITY\SYSTEM due to insufficient control during autoupdate.

Race condition in Dr.Web Security Space Pro 6.0.0.03100 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 Dr.Web 5.0.2.03300, eSafe 7.0.17.0, McAfee Gateway (formerly Webwasher) 2010.1C, Rising Antivirus 22.83.00.03, 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 ei_version 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 CAB file parser in Dr.Web 5.0.2.03300, Trend Micro HouseCall 9.120.0.1004, Kaspersky Anti-Virus 7.0.0.125, Sophos Anti-Virus 4.61.0, Trend Micro AntiVirus 9.120.0.1004, McAfee Gateway (formerly Webwasher) 2010.1C, Emsisoft Anti-Malware 5.1.0.1, CA eTrust Vet Antivirus 36.1.8511, Antiy Labs AVL SDK 2.0.3.7, Antimalware Engine 1.1.6402.0 in Microsoft Security Essentials 2.0, Rising Antivirus 22.83.00.03, Ikarus Virus Utilities T3 Command Line Scanner 1.1.97.0, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via a CAB file with a modified coffFiles field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different CAB parser implementations.

The ELF file parser in Fortinet Antivirus 4.2.254.0, eSafe 7.0.17.0, Dr.Web 5.0.2.03300, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified e_version 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.

DrWeb Anti-virus 4.44.0.09170, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.
