CVE-2020-35702 Information

Description

DISPUTED 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.
