Multiple security issues have been found in the GD Graphics Library.
They may lead to the execution of arbitrary code or causing application crash.
CVE-2016-9317
Signed integer overflow in gd_io.c
CVE-2016-10167
Improper handling of issing image data can cause crash
CVE-2016-10168
GD2 stores the number of horizontal and vertical chunks as words (i.e.
2 byte unsigned). These values are multiplied and assigned to an int when reading the image, what can cause integer overflows.
For Debian 7 ‘Wheezy’, these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u8.
We recommend that you upgrade your libgd2 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
