Bug 611444 – <app-text/mupdf-1.10a-r2: NULL pointer dereference

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Ian Zimmerman 2017-03-03 00:38:45 UTC]

Upstream commit message says:

Bug 697500: Fix NULL ptr access.

Cope better with errors during rendering - avoid letting the
gstate stack get out of sync.

This avoids us ever getting into the situation of popping
a clip when we should be popping a mask or a group. This was
causing an unexpected case in the painting.

This is CVE-2017-5991, and DSA (Debian advisory) DSA-3797.


Reproducible: Always

I don't see this one handled along with bug 608702 or bug 608712 nor immediately recognize patch in files, so setting [upstream/ebuild] for now

Because we have to do one GLSA for bug 614044 I'll add this one to the same advisory.
