- Date Reported:
- 29 Jan 2017
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2016-9317, CVE-2016-10167, CVE-2016-10168.
- More information:
Multiple security issues have been found in the GD Graphics Library. They may lead to the execution of arbitrary code or causing application crash.
Signed integer overflow in gd_io.c
Improper handling of issing image data can cause crash
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.
