CVE-2015-8472
It was discovered that the original fix for CVE-2015-8126 was incomplete and did not detect a potential overrun by applications using png_set_PLTE directly. A remote attacker can take advantage of this flaw to cause a denial of service (application crash).
CVE-2015-8540
Xiao Qixue and Chen Yu discovered a flaw in the png_check_keyword function. A remote attacker can potentially take advantage of this flaw to cause a denial of service (application crash).
For the oldstable distribution (wheezy), these problems have been fixed in version 1.2.49-1+deb7u2.
For the stable distribution (jessie), these problems have been fixed in version 1.2.50-2+deb8u2.
We recommend that you upgrade your libpng packages.");
