GCVE-110-MAGEIA-2016-215

Updated libgd packages fix security vulnerabilities: The gdImageScaleTwoPass function in gd_interpolation.c in libgd before 2.2.0 uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function (CVE-2015-8877). While creating an XBM image (imagexbm) with an user supplied name, libgd before 2.2.0 did not check the vsnprintf return value, so an application might trust this length and read more memory than it should, causing a read-out-of boundaries, leaking stack memory (CVE-2016-5116).
