Last modified
CVE-2020-35702 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. EPSS estimates a 0.86% chance of exploitation in the next 30 days.
Description
DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects
