AlienVault OTX Vulnerabilities

AlienVault OTX Malware

xfig

Xfig v3.2.8 was discovered to contain a NULL pointer dereference when calling XGetWMHints(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server or window manager.

CVE-2023-45920 identifies a NULL pointer dereference vulnerability in Xfig version 3.2.8, specifically occurring when the application calls the XGetWMHints() function. This function interacts with the X Window System to retrieve window manager hints, and the dereference of a NULL pointer leads to a crash of the Xfig application, resulting in a denial of service condition. The vulnerability is classified under CWE-476 (NULL Pointer Dereference). The CVSS v3.1 score is 4.2 (medium), reflecting that exploitation requires local access (AV:L), low attack complexity (AC:L), high privileges (PR:H), and user interaction (UI:R). The impact is limited to availability (A:H) with no confidentiality or integrity loss. The vulnerability is disputed because it is generally expected that an X application should not continue running normally if the X server or window manager behaves anomalously, which may limit the practical exploitability. No patches or known exploits have been reported, indicating this is a newly published issue with limited active threat. The vulnerability primarily affects environments running Xfig 3.2.8 on Unix-like systems with X Window System, often used in academic, research, and legacy graphical diagramming contexts.
