Kaspersky Anti-Virus (KAV) and Internet Security 7.0 build 125 do not properly validate certain parameters to System Service Descriptor Table (SSDT) and Shadow SSDT function handlers, which allows local users to cause a denial of service (crash) via the (1) NtUserSendInput, (2) LoadLibraryA, (3) NtOpenProcess, (4) NtOpenThread, (5) NtTerminateProcess, (6) NtUserFindWindowEx, and (7) NtUserBuildHwndList kernel SSDT hooks in kylif.sys; the (8) NtDuplicateObject (DuplicateHandle) kernel SSDT hook; and possibly other kernel SSDT hooks. NOTE: the NtCreateSection vector is covered by CVE-2007-5043.1. NOTE: the vendor disputes that the DuplicateHandle vector is a vulnerability in their code, stating that "it is not an error in our code, but an obscure method for manipulating standard Windows routines to circumvent our self-defense mechanisms."
Kaspersky Internet Security 7.0.0.125 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to (1) cause a denial of service (crash) and possibly gain privileges via the NtCreateSection kernel SSDT hook or (2) cause a denial of service (avp.exe service outage) via the NtLoadDriver kernel SSDT hook. NOTE: this issue may partially overlap CVE-2006-3074.
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.
The StartUploading function in KL.SysInfo ActiveX control (AxKLSysInfo.dll) in Kaspersky Anti-Virus 6.0 and Internet Security 6.0 before Maintenance Pack 2 build 6.0.2.614 allows remote attackers to read arbitrary files by triggering an outbound anonymous FTP session that invokes the PUT command. NOTE: this issue might be related to CVE-2007-1112.
Unspecified vulnerability in KLIF (klif.sys) 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 local users to gain Ring-0 privileges via unspecified vectors.
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.
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.
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.
