> (2) HIGH: Acer Notebooks ActiveX Control Arbitrary Command Execution
> Affected:
> All Acer Notebooks running Windows
> 
> Description: Acer, a Taiwan based company, is a leading Notebook
> producer with a dominant presence in the Europe, Asia and 
> Africa (EMEA)
> market. Acer Notebooks ship with "LunchApp.APlunch" ActiveX 
> control that
> is marked as safe for scripting. This ActiveX control supports "Run"
> method that can be used to run any command (with arbitrary parameters)
> on an Acer notebook remotely. A specially crafted webpage or an HTML
> email can exploited this flaw to compromise Acer Notebooks. The
> discoverer has posted a proof-of-concept exploit, and tested the
> presence of this ActiveX control on an older as well as a more recent
> Acer model.
> 
> Status: Acer has not confirmed. A workaround is to set the 
> kill bit for
> the LunchApp.APlunch ActiveX control's UUID:
> D9998BD0-7957-11D2-8FED-00606730D3AA.
> 
> Council Site Actions: The affected software and/or

> Affected:
> BrightStor ARCserver Backup version 11.5 and possibly prior
> 
> Description: Computer Associates BrightStor ARCserve Backup products
> provide backup services for Windows, NetWare, Linux and UNIX. The
> products contains a buffer overflow that can be triggered by 
> a specially
> crafted RPC request to the port 6502/tcp. The flaw can be exploited to
> execute arbitrary code with SYSTEM privileges. The technical details
> have not been publicly posted yet.
> 
> Status: CA is aware of this issue and is working on a fix. A 
> workaround,
> in the meanwhile, is to block the requests to port 6502/tcp at the
> network perimeter.
> 
> Special Note: CA backup products have been reported to 
> contain multiple
> vulnerabilities for the past few years. SANS recommends you 
> to block all
> the ports that are opened by the software at the network perimeter. A
> list of the ports to block may be found at:

> (5) HIGH: GNU Radius Format String Vulnerability
> Affected:
> GNU Radius versions prior to 1.4
> 
> Description: GNU Radius is a server for user authentication and
> accounting. The server supports SQL databases for authentication and
> accounting. The Radius server contains a format string vulnerability
> when it is compiled with a SQL back-end, and the SQL accounting is
> turned on. The flaw can be exploited by unauthenticated attackers to
> execute arbitrary code on the server with typically root 
> privileges. The
> technical details can be extracted by examining the fixed and the
> vulnerable versions of the server code.
> 
> Status: GNU has released version 1.4 to fix this flaw. Note that the
> FreeBSD and Gentoo Linux versions are vulnerable in their default
> configuration.

> (7) HIGH: NetGear WG311v1 Wireless Driver SSID Buffer Overflow
> Affected:
> NetGear WG311v1 wireless driver version 2.3.1 10 and possibly prior
> 
> Description: The NetGear WG311v1 device driver, used to 
> control NetGear
> wireless cards, contains a buffer overflow vulnerability. By sending a
> specially-crafted 802.11 (WiFi) frame containing an overly long SSID,
> an attacker could exploit this buffer overflow and take 
> complete control
> of the vulnerable system. No authentication is required, and attackers
> need only be within wireless range of the vulnerable system. Because
> this vulnerability lies within the processing of probe 
> response packets,
> the victim does not need to explicitly connect to a malicious wireless
> network to be exploited. This driver is primarily designed 
> for Microsoft
> Windows systems, but it is believed to be compatible with the
> "NdisWrapper" cross-platform driver framework, making it 
> possible to run
> this driver under Linux (and possibly other operating systems) on the
> Intel platform. This vulnerability was discovered as part of a project
> to discover bugs in various operating systems' kernels. A working
> exploit is available for this vulnerability. This vulnerability is
> similar to several discovered for other NetGear wireless 
> device drivers
> that were documented in a previous issue of @RISK.
> 
> Status: NetGear has not confirmed, no updates available.

> Platform: Network Device
> Title: NetGear MA521 Wireless Driver Long Beacon Probe Buffer Overflow
> Description: NetGear MA521 Wireless device is affected by a stack
> based buffer overflow issue because the driver fails to bounds check
> user-supplied data before copying it into an insufficiently sized
> memory buffer. Version 5.148.724.2003 of the MA521nd5.SYS driver is
> affected.

> Title: NetGear WG111v2 Wireless Driver Long Beacon Buffer Overflow
> Description: NetGear WG111v2 Wireless device is vulnerable to a stack
> based buffer overflow issue when the driver attempts to process 802.11
> Beacon frames containing excessively long information elements.
> Netgear version 5.1213.6.316 of the WG111v2.SYS driver is vulnerable.
