New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.4
Synopsis
The remote Debian host is missing a security-related update.
Description
Multiple stack-based buffer overflows were discovered in libupnp4, 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 libupnp4 could generate a buffer overflow, overwriting the stack, leading to the daemon crash and possible remote code execution.
Solution
Upgrade the libupnp4 packages.
For the stable distribution (squeeze), these problems have been fixed in version 1.8.0~svn20100507-1+squeeze1.
