Cisco releases bundle of router security patches

摘要

Cisco has issued a set of security patches for the Internet Operating System software used to power its routers and switches.The patches were published last Wednesday, the date Cisco had previously set aside as the latest release date for its twice-yearly IOS patches. Cisco also published 12 security advisories describing the bugs, noting that many of these vulnerabilities could be exploited by attackers to crash an IOS device. One of the bugs, a flaw in SNMP, could be exploited by an attacker to seize control of the router. However, only specially configured Cisco uBR10012 series devices, used by telecommunications companies to connect broadband customers to the Internet, are affected by the flaw, Cisco said. Symantec rates this flaw critical and advised users of these devices who have configured their routers for linecard redundancy apply the patches as soon as possible. Other bugs that were patched affect Cisco's multicast, SSL processing, and Session Initiation Protocol software.
