Cisco AnyConnect Secure Mobility Client 3.0 before 3.0.08057 allows remote authenticated users to cause a denial of service (vpnagentd process crash) via a crafted packet, aka Bug ID CSCty01670.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 and 3.x before 3.0 MR8 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtw48681.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 on Windows, and 2.x before 2.5 MR6 and 3.x before 3.0 MR8 on Mac OS X and Linux, does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug ID CSCtw47523.

The HostScan downloader implementation in Cisco AnyConnect Secure Mobility Client 3.x before 3.0 MR8 and Cisco Secure Desktop before 3.6.6020 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtx74235.

A certain Java applet in the VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 3.x before 3.0 MR7 on 64-bit Linux platforms does not properly restrict use of Java components, which allows remote attackers to execute arbitrary code via a crafted web site, aka Bug ID CSCty45925.

The Start Before Logon (SBL) functionality in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.3.254 on Windows, and on Windows Mobile, allows local users to gain privileges via unspecified user-interface interaction, aka Bug ID CSCta40556.

The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.3.185 on Windows, and on Windows Mobile, downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a certain ActiveX control in vpnweb.ocx, aka Bug ID CSCsy00904.

The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.5.3041, and 3.0.x before 3.0.629, on Linux and Mac OS X downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a Java applet, aka Bug ID CSCsy05934.

F-Secure Internet Security 2010 and earlier; Anti-Virus for Microsoft Exchange 9 and earlier, and for MIMEsweeper 5.61 and earlier; Internet Gatekeeper for Windows 6.61 and earlier, and for Linux 4.02 and earlier; Anti-Virus 2010 and earlier; Home Server Security 2009; Protection Service for Consumers 9 and earlier, for Business - Workstation security 9 and earlier, for Business - Server Security 8 and earlier, and for E-mail and Server security 9 and earlier; Mac Protection build 8060 and earlier; Client Security 9 and earlier; and various Anti-Virus products for Windows, Linux, and Citrix; does not properly detect malware in crafted (1) 7Z, (2) GZIP, (3) CAB, or (4) RAR archives, which makes it easier for remote attackers to avoid detection.
