Description Sam Fowler 2018-08-23 23:57:13 EDT

libgd through version 2.2.5 is vulnerable to a double free in the src/gd_bump.c:gdImageBmpPtr() function when parsing a crafted JPEG. An attacker could exploit this to cause a crash or potentially execute arbitrary code.

RHEL7 is using gd-2.0.35, which is a release before BMP support was merged in. RHEL7 and before not affected.
