Description Laura Pardo 2018-05-24 20:45:26 UTC 
In MuPDF 1.12.0 and earlier, multiple use of uninitialized values in the PDF parser could allow an attacker to cause a denial of service (crash) or influence program flow via a crafted file.

Comment 1 Laura Pardo 2018-05-24 20:48:11 UTC 
Created mupdf tracking bugs for this issue:

Affects: fedora-all [bug 1582316]
Comment 2 Michael J Gruber 2018-06-10 11:48:15 UTC 
Fixed in 1.13.0

Closing here since 1582316 is bogus (tracker should be here and depend on various blockers against mupdf, not the other way round).
