-Subject: [PATCH] jbig2dec: Make tests expect that some test files return white
- image.
-
-Previously these tests would just error out and jbig2dec would not
-return any output file at all. Now, jbig2dec parses as much as
-possible, while emitting warning/error messages. In the case of a
-few of the test files the end result is a white image.

-Subject: [PATCH] jbig2dec: Handle under-/overflow detection and messaging
- better.
-
-Previously SYMWIDTH was capped too early in order to prevent underflow
-Moreover TOTWIDTH was allowed to overflow.
-
-Now the value DW is checked compared to SYMWIDTH, preventing over
-underflow and overflow at the correct limits, and an overflow
-check has been added for TOTWIDTH.

media-libs/jbig2dec: security bump to 0.18
Bump to 0.18, but while we're here,
add support for newer Pythons at build time.
We include two additional upstream patches
post-release which look security-relevant.
Bug: https://bugs.gentoo.org/719730

+Subject: [PATCH] jbig2dec: Handle under-/overflow detection and messaging
+ better.
+
+Previously SYMWIDTH was capped too early in order to prevent underflow
+Moreover TOTWIDTH was allowed to overflow.
+
+Now the value DW is checked compared to SYMWIDTH, preventing over
+underflow and overflow at the correct limits, and an overflow
+check has been added for TOTWIDTH.

+Subject: [PATCH] jbig2dec: Make tests expect that some test files return white
+ image.
+
+Previously these tests would just error out and jbig2dec would not
+return any output file at all. Now, jbig2dec parses as much as
+possible, while emitting warning/error messages. In the case of a
+few of the test files the end result is a white image.
