Part I for this issue has been compiled by Rohan Kotian at TippingPoint, a division of 3Com, 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/cva/#process
Description: Apple iTunes, a popular digital media player Apple Mac OS X and Microsoft Windows, is vulnerable to a buffer overflow error. A specially crafted playlist ".pls" files can be used to trigger this vulnerability. The specific flaw is a boundary error while processing ".pls" files. Successful exploitation might allow an attacker to execute arbitrary code in the context of the vulnerable application or it might lead to a denial-of-service condition. An attacker will have to entice the user into opening a malformed playlist file; either by sending the malicious file as an e-mail attachment or by sending a link to a malformed playlist file in an e-mail message. Some technical details for the vulnerability are publicly available.
Status: Vendor confirmed, updates available.
Description: VLC media player, an open source and a popular cross-platform media player from VideoLAN project, has been identified with multiple buffer overflow vulnerabilities. a) There is a buffer overflow error in the "ASF_ObjectDumpDebug()" function in "modules/demux/asf/libasf.c". A specially crafted ASF file can be used to trigger this vulnerability. b) There is a buffer overflow error in the "AVI_ChunkDumpDebug_level()" function in "modules/demux/avi/libavi.c". A specially crafted AVI file can be used to trigger this vulnerability. c) There is a buffer overflow error in the "__MP4_BoxDumpStructure()" function in "modules/demux/mp4/libmp4.c". A specially crafted MP4 file can be used to trigger this vulnerability. Successful exploitation in either of the exploits might allow an attacker to execute arbitrary code in the context of the vulnerable application or to create a denial-of-service condition. Full technical details for this vulnerability are publicly available.
Status: Vendor confirmed, updates available.
Description: Cisco Internetwork Operating System (IOS) is a software package where routing, internetworking and telecommunications are integrated with a multitasking operating system. Multiple vulnerabilities have been reported in Cisco IOS. Buffer overflow, denial-of-service and security bypass are some of the vulnerabilities that have been identified in this product. In some cases on successful exploitation an attacker might execute arbitrary code whereas in some cases an attacker might cause a denial-of-service condition. Some technical details for some of the vulnerabilities are publicly available.
Status: Vendor confirmed, updates available.
Qualys (www.qualys.com) Week 39, 2009 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 7461 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
