Scientific Linux Security Update : libpng on SL7.x x86_64
High Nessus Plugin ID 87585
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. However, the exact impact is dependent on the application using the library. (CVE-2015-8126, CVE-2015-8472)
SolutionUpdate the affected packages.
