Debian DSA-2614-1 : libupnp - several vulnerabilities
Critical Nessus Plugin ID 64395
The remote Debian host is missing a security-related update.
Multiple stack-based buffer overflows were discovered in libupnp, a library used for handling the Universal Plug and Play protocol. HD Moore from Rapid7 discovered that SSDP queries where not correctly handled by the unique_service_name() function. An attacker sending carefully crafted SSDP queries to a daemon built on libupnp could generate a buffer overflow, overwriting the stack, leading to the daemon crash and possible remote code execution.
Upgrade the libupnp packages. For the stable distribution (squeeze), these problems have been fixed in version 1:1.6.6-5+squeeze1.
