CVE-2008-1944

18
FAUCET Score

CVE-2008-1944 describes a buffer overflow vulnerability in the XenSource Xen Para-Virtualized Framebuffer (PVFB) Message 3.0 through 3.0.3, affecting various Red Hat and XenSource products. A local attacker can exploit this by sending "bogus screen updates" due to missing message format validation, leading to a denial of service (SDL crash) and potentially arbitrary code execution. With a CVSS score of 7.2 (high severity), it has a low attack complexity and requires local access, but can result in complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion, and it is not listed on the CISA KEV catalog.
