Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2018-17100)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to int32 overflow when insufficient validation of user-supplied input processed by the multiply_ms() function, as defined in the tools/ppm2tiff.c source code file. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
