Description:
Thomas Pollet has reported a vulnerability in CUPS, which potentially can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to two integer overflow errors in filter/image-png.c when processing PNG files. These can be exploited to cause a heap-based buffer overflow via overly large width and height PNG fields.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in version 1.3.7. Prior versions may also be affected.
Solution:
Update to version 1.3.8.
Provided and/or discovered by:
