The NDIS-TDI Hooking Engine, as used in the (1) KLICK (KLICK.SYS) and (2) KLIN (KLIN.SYS) device drivers 2.0.0.281 for in Kaspersky Labs Anti-Virus 6.0.0.303 and other Anti-Virus and Internet Security products, allows local users to execute arbitrary code via crafted Irp structure with invalid addresses in the 0x80052110 IOCTL.

Kaspersky Anti-Hacker 1.8.180, when Stealth Mode is enabled, allows remote attackers to obtain responses to ICMP (1) timestamp and (2) netmask requests, which is inconsistent with the documented behavior of Stealth Mode.

klif.sys in Kaspersky Internet Security 6.0 and 7.0, Kaspersky Anti-Virus (KAV) 6.0 and 7.0, KAV 6.0 for Windows Workstations, and KAV 6.0 for Windows Servers does not validate certain parameters to the (1) NtCreateKey, (2) NtCreateProcess, (3) NtCreateProcessEx, (4) NtCreateSection, (5) NtCreateSymbolicLinkObject, (6) NtCreateThread, (7) NtDeleteValueKey, (8) NtLoadKey2, (9) NtOpenKey, (10) NtOpenProcess, (11) NtOpenSection, and (12) NtQueryValueKey hooked system calls, which allows local users to cause a denial of service (reboot) via an invalid parameter, as demonstrated by the ClientId parameter to NtOpenProcess.

Kaspersky Antivirus 5.0.5 and 5.5.3 allows remote attackers to cause a denial of service (CPU and memory consumption) via unknown attack vectors.

Heap-based buffer overflow in Kaspersky Anti-Virus Engine, as used in Kaspersky Personal 5.0.227, Anti-Virus On-Demand Scanner for Linux 5.0.5, and F-Secure Anti-Virus for Linux 4.50 allows remote attackers to execute arbitrary code via a crafted CHM file.

Unquoted Windows search path vulnerability in Kaspersky Anti-Virus 5.0 might allow local users to gain privileges via a malicious "program.exe" file in the C: folder.

Multiple interpretation error in Kaspersky 5.0.372 allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Multiple interpretation error in unspecified versions of Kaspersky Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.

Heap-based buffer overflow in Kaspersky Antivirus (KAV) 5.0 and Kaspersky Personal Security Suite 1.1 allows remote attackers to execute arbitrary code via a CAB file with large records after the header.

Kaspersky Anti-Virus for Unix/Linux File Servers 5.0-5 uses world-writable permissions for the (1) log and (2) license directory, which allows local users to delete log files, append to arbitrary files via a symlink attack on kavmonitor.log, or delete license keys and prevent keepup2date from properly executing.
