CRITICAL 9.8

DescriptionNVD

The Pictview image processing library embedded in the ActivePDF toolkit through 2018.1.0.18321 is prone to multiple out of bounds write and sign errors, allowing a remote attacker to execute arbitrary code on vulnerable applications using the ActivePDF Toolkit to process untrusted images.

AnalysisAI

The Pictview image processing library embedded in the ActivePDF toolkit through 2018.1.0.18321 is prone to multiple out of bounds write and sign errors, allowing a remote attacker to execute. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and 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. The Pictview image processing library embedded in the ActivePDF toolkit through 2018.1.0.18321 is prone to multiple out of bounds write and sign errors, allowing a remote attacker to execute arbitrary code on vulnerable applications using the ActivePDF Toolkit to process untrusted images. Affected products include: Activepdf Activepdf Toolkit. Version information: through 2018.1.0.18321.

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).
