Unspecified vulnerability in Kaspersky Online Scanner 7.0 has unknown impact and attack vectors, as demonstrated by a certain module in VulnDisco Pack Professional 8.8, (1) "Kaspersky Online Antivirus Scanner 7.0 exploit (Linux)" and (2) "Kaspersky Online Antivirus Scanner 7.0 exploit (Windows)." NOTE: as of 20090909, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.

A certain ActiveX control in (1) OScan8.ocx and (2) Oscan81.ocx in BitDefender Online Anti-Virus Scanner 8.0 allows remote attackers to execute arbitrary code via a long argument to the InitX method that begins with a "%%" sequence, which is misinterpreted as a Unicode string and decoded twice, leading to improper memory allocation and a heap-based buffer overflow.

The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.

Integer overflow in the packed PE file parsing implementation in BitDefender products before 20060829, including Antivirus, Antivirus Plus, Internet Security, Mail Protection for Enterprises, and Online Scanner; and BitDefender products for Microsoft ISA Server and Exchange 5.5 through 2003; allows remote attackers to execute arbitrary code via a crafted file, which triggers a heap-based buffer overflow, aka the "cevakrnl.xmd vulnerability."

The Content Scanner Server in F-Secure Anti-Virus for Microsoft Exchange 6.21 and earlier, F-Secure Anti-Virus for Microsoft Exchange 6.01 and earlier, and F-Secure Internet Gatekeeper 6.32 and earlier allow remote attackers to cause a denial of service (service crash due to unhandled exception) via a certain malformed packet.

securetar, as used in AMaViS shell script 0.2.1 and earlier, allows users to cause a denial of service (CPU consumption) via a malformed TAR file, possibly via an incorrect file size parameter.

The AMaViS virus scanner 0.2.0-pre4 and earlier allows remote attackers to execute arbitrary commands as root via an infected mail message with shell metacharacters in the reply-to field.
