The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Untrusted search path vulnerability in F-Secure Online Scanner allows remote attackers to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse DLL that is located in the same folder as F-SecureOnlineScanner.exe.

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.

Multiple format string vulnerabilities in the kavwebscan.CKAVWebScan ActiveX control (kavwebscan.dll) in Kaspersky Online Scanner before 5.0.98 allow remote attackers to execute arbitrary code via format string specifiers in "various string formatting functions," which trigger heap-based buffer overflows.

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."
