CVE-2019-9959: Debian Linux

Medium severity, CVSS 6.5. EPSS: 1.9% chance of exploitation in the next 30 days.

The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.
