Comment 2 Mauro Matteo Cascella 2020-02-10 13:57:40 UTC

Upstream fix:
https://gitlab.freedesktop.org/poppler/poppler/commit/b224e2f5739fe61de9fa69955d016725b2a4b78d

Comment 3 Mauro Matteo Cascella 2020-02-10 15:13:35 UTC

Function tilingPatternFill() was defined in SplashOutputDev.cc in Poppler upstream version 0.17.0 with commit https://gitlab.freedesktop.org/poppler/poppler/commit/abf167af.

Red Hat Enterprise Linux 5 and 6 ship older versions of Poppler (0.5.4 and 0.12.4 respectively) that do not include the vulnerable function and, consequently, are not affected by this flaw.

Comment 4 Mauro Matteo Cascella 2020-02-10 15:17:15 UTC

Statement:

This flaw did not affect the versions of Poppler as shipped with Red Hat Enterprise Linux 5 and 6, as they did not include the vulnerable code.
