The bug was discovered by Kamil Frankowicz which said to have tested it against the current git head. The same testcase does not crash the current stable 1.10a, but I can confirm (with a round of fuzzing on 1.10a) that stable is affected. No fix atm. Details: https://bugs.ghostscript.com/show_bug.cgi?id=697515 Reproducer for 1.10a: https://github.com/asarubbo/poc/blob/master/00148-mupdf-heapoverflow-fz_subsample_pixmap -- Agostino Sarubbo Gentoo Linux Developer
