This is an integer underflow issue in an integer overflow check, which guards against buffer over-read. This can easily trigger crash. The problem was introduced in the following commit: http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=ba931be2 Additionally, prior to upstream version 2.5, affected code was only built and used when FT_CONFIG_OPTION_OLD_INTERNALS macro was not defined. It was defined by default in upstream versions prior to 2.4.12: http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=e4ecce3b The freetype packages in Red Hat Enterprise Linux are based on older upstream versions and do not override this upstream setting, i.e. they define FT_CONFIG_OPTION_OLD_INTERNALS. Therefore, they were not affected by this issue, or the problem commit e4ecce3b attempted to address. Statement: This issue did not affect the versions of freetype as shipped with Red Hat Enterprise Linux 5, 6, and 7. -- You are receiving this mail because: You are on the CC list for the bug.
