PART I Critical Vulnerabilities Part I for this issue has been compiled by Josh Bronson at TippingPoint, a division of HP, as a by-product of that company's continuous effort to ensure that its intrusion prevention products effectively block exploits using known vulnerabilities. TippingPoint's analysis is complemented by input from a council of security managers from twelve large organizations who confidentially share with SANS the specific actions they have taken to protect their systems. A detailed description of the process may be found at http://www.sans.org/newsletters/risk/#process

Description: Mozilla has released patches to address multiple security vulnerabilities in its Firefox web browser. The vulnerabilities include unspecified memory corruption issues, a use-after-free error in AttributeChildRemoved() that can be exploited by removing child nodes from the nsDOMAttribute node, an unspecified vulnerability in the handling of Ogg Vorbis multimedia files, and a memory corruption vulnerability in XSLT stylesheets. By enticing a target to view a malicious site, an attacker can exploit these vulnerabilities in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Symantec has released a patch to address a vulnerability in its pcAnywhere product. PcAnywhere consists of a server and a client that allow a user to connect to a computer and control it remotely. The server component accepts requests for authentication on port 5631 and copies the user-controlled username in these requests to a fixed-length 264-byte buffer. By sending an overlong username, an attacker can exploit this buffer overflow in order to execute arbitrary code on the target's machine with SYSTEM-level privileges.
Status: vendor confirmed, updates available
Part II -- Comprehensive List of Newly Discovered Vulnerabilities from Qualys (www.qualys.com) This list is compiled by Qualys ( www.qualys.com ) as part of that company's ongoing effort to ensure its vulnerability management web service tests for all known vulnerabilities that can be scanned. As of this week Qualys scans for 13127 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
