Debian Security Advisory DSA-3443-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso

Package : libpng
CVE ID : CVE-2015-8472 CVE-2015-8540
Debian Bug : 807112 807694
Several vulnerabilities have been discovered in the libpng PNG library.
The Common Vulnerabilities and Exposures project identifies the
following problems:
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.
