Linux Distros Unpatched Vulnerability : CVE-2017-7961

high Nessus Plugin ID 221567

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - The cr_tknzr_parse_rgb function in cr-tknzr.c in libcroco 0.6.11 and 0.6.12 has an outside the range of representable values of type long undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted CSS file.
 NOTE: third-party analysis reports This is not a security issue in my view. The conversion surely is truncating the double into a long value, but there is no impact as the value is one of the RGB components.
 (CVE-2017-7961)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
