Now libpng better detects a bad png files, and this is not a bug of course, but rather a sign that the image should be fixed. pngfix /usr/share/perl5/Authen/Captcha/images/background5.png IDAT OK default 15 15 7197 7035 /usr/share/perl5/Authen/Captcha/images/background5.png HEAD ERR 00 libpng Success Success IDAT:_chunk_data_is_too_large /usr/share/perl5/Authen/Captcha/images/background5.png I'm raising the severity to serious, because this seems to be a serious enough bug, even more because the package can't rebuild now (fails testsuite, e.g. in Ubuntu, while on Debian for some bug the error is not caught in dh_auto_test) e.g. Ubuntu failure: make[1]: Entering directory '/build/libauthen-captcha-perl-1.024' PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(1, 'blib/lib', 'blib/arch')" t/*.t GD Warning: gd-png: fatal libpng error: IDAT: chunk data is too large GD Warning: gd-png error: setjmp returns error condition 1 gdImageCreateFromPng error at /usr/lib/x86_64-linux-gnu/perl5/5.26/GD/Image.pm line 178. t/1.t .. 1..32 # Running under perl version 5.026000 for linux # Current time local: Wed Sep 13 06:43:10 2017 # Current time GMT: Wed Sep 13 06:43:10 2017 # Using Test.pm version 1.30 ok 1 ok 2 ok 3 ok 4 ok 5 ok 6 ok 7 ok 8 ok 9 ok 10 ok 11 ok 12 ok 13 ok 14 ok 15 ok 16 ok 17 ok 18 ok 19 ok 20 ok 21 ok 22 ok 23 ok 24 Dubious, test returned 255 (wstat 65280, 0xff00) Failed 8/32 subtests Test Summary Report ------------------- t/1.t (Wstat: 65280 Tests: 24 Failed: 0) Non-zero exit status: 255 Parse errors: Bad plan.
