Dear Release Team,
I have just uploaded atril 1.20.3-1+deb10u1 to Debian buster with the
following changes:
+ [ Martin Wimpress ]
+ * debian/patches:
+ + Add 0001_prevent_no_doc_segfault.patch. Prevent segfaults when no document
+ is loaded.
See upstream issue: https://github.com/mate-desktop/atril/issues/357
When one loaded atril with no document and started playing with the
application settings, atril would segfault.
+ + Add 0002_CVE-2019-1010006.patch. Fix buffer overflow. (CVE-2019-1010006)
This is a low security issue, but not tagged as no-dsa on the security
tracker. However, getting the other two patches into buster had prio and
thus I took the buster-pu upload path for this.
+ [ Mike Gabriel ]
+ * debian/patches:
+ + Add CVE-2019-11459.patch. tiff: Handle failure from
+ TIFFReadRGBAImageOriented. (Closes: #927821).
+ + Rebase 0001_prevent_no_doc_segfault.patch.
Security issue marked as unimportant, still something that deserves a fix via
buster-pu.
light+love,
Mike

+Subject: [PATCH] prevent segfaults when no document loaded
+
+See the issue report for a description of the bug. The root cause is
+dereferencing of NULL pointers, specifically the priv->document member of
+EvWindow structures when no document is loaded. This commit adds checks
+for a NULL value of priv->document at all the points in the file
+shell/ev-window.c where this pointer was previously dereferenced without
+being checked.
+
+Fixes 357 (https://github.com/mate-desktop/atril/issues/357)
