Fedora Project

  • Updated libpng10 to 1.0.55 in Rawhide only, as there appears to be a regression in the Makefile regarding creation of libpng.sym that breaks the build; I patched that part of the Makefile back to the same as it was in 1.0.54 for this build

    • Fixed uninitialized memory read in png_format_buffer() (CVE-2011-2501, related to CVE-2004-0421)

    • Pass "" instead of '\0' to png_default_error() in png_err()

    • Check for up->location !PNG_AFTER_IDAT when writing unknown chunks before IDAT

    • Ported bug-fix in pngrtran.c from 1.5.3: when expanding a paletted image, always expand to RGBA if transparency is present

    • Check for integer overflow in png_set_rgb_to_gray()

    • Check for sCAL chunk too short

Local Packages

  • Updated libpng10 to 1.0.55 as per the Fedora version

  • Updated perl-File-HomeDir to 0.98:

    • Updating to Module::Install 1.01

    • If Win32::GetFolderPath returns a \\UNC type path, do not do the normal -d sanity check, as strange and unusual bugs may occur

  • Updated perl-Pod-Coverage-TrustPod to 0.100001:

    • Anchor the regex at both ends when matching symbols: /\A...\z/

  • Updated perl-XML-LibXML to 1.78:

    • Change t/02parse.t to test for the localized error message (CPAN RT#69248)

    • Fix the skip() and 'plan skip_all' syntax in t/06elements.t and t/49global_extent.t

    • Convert more test scripts from Test.pm to Test::More
