Vulnerability Note VU#230505Cisco IOS LPD buffer overflow vulnerabilityOverviewThe Cisco IOS Line Printer Daemon contains a buffer overflow vulnerability. If successfully exploited, this vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition .I. DescriptionThe Cisco IOS includes support for the UNIX Line Printer Daemon (LPD) protocol. The LPD service listens on 515/tcp and is not enabled by default.The IOS LPD service does not properly check the length of the hostname of the router. This error may result in a buffer overflow.
