Amazon Linux AMI : libpng (ALAS-2015-615)
high Nessus Plugin ID 87341
Language:
Synopsis
The remote Amazon Linux AMI host is missing a security update.Description
It 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-2015-7981)An array-indexing error was discovered in the png_convert_to_rfc1123() function of libpng. An attacker could possibly use this flaw to cause an out-of-bounds read by tricking an unsuspecting user into processing a specially crafted PNG image. (CVE-2015-8472)
Solution
