CVE-2020-35702: Freedesktop Poppler

High severity, CVSS 7.8. EPSS: 0.9% chance of exploitation in the next 30 days.

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

Affected products

• Freedesktop Poppler: version 20.12.1 only
