Heap-based buffer overflow in the arj.ppl module in the OnDemand Scanner in Kaspersky Anti-Virus, Anti-Virus for Workstations, and Anti-Virus for File Servers 6.0, and Internet Security 6.0 before Maintenance Pack 2 build 6.0.2.614 allows remote attackers to execute arbitrary code via crafted ARJ archives.
Kaspersky Anti-Virus 6.0 and Internet Security 6.0 exposes unsafe methods in the (a) AXKLPROD60Lib.KAV60Info (AxKLProd60.dll) and (b) AXKLSYSINFOLib.SysInfo (AxKLSysInfo.dll) ActiveX controls, which allows remote attackers to "download" or delete arbitrary files via crafted arguments to the (1) DeleteFile, (2) StartBatchUploading, (3) StartStrBatchUploading, or (4) StartUploading methods.
Integer overflow in the _NtSetValueKey function in klif.sys in Kaspersky Anti-Virus, Anti-Virus for Workstations, Anti-Virus for File Server 6.0, and Internet Security 6.0 before Maintenance Pack 2 build 6.0.2.614 allows context-dependent attackers to execute arbitrary code via a large, unsigned "data size argument," which results in a heap overflow.
Kaspersky Anti-Virus for Linux Mail Servers 5.5.10 allows remote attackers to bypass virus detection by inserting invalid characters into base64 encoded content in a multipart/mixed MIME file, as demonstrated with the EICAR test file.
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.
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."
