AnalysisAI
A maliciously crafted TIFF and PCX file can be forced to read and write beyond allocated boundaries when parsing the TIFF and PCX file for based overflow. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A maliciously crafted TIFF and PCX file can be forced to read and write beyond allocated boundaries when parsing the TIFF and PCX file for based overflow. This vulnerability can be exploited to execute arbitrary code. Affected products include: Autodesk Autocad, Autodesk Design Review.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
