CVE-2017-7961 low priority: Ubuntu including 1 source packages (libcroco), 12 status rows across 12 suites (artful, bionic, cosmic, disco, eoan, focal, precise, trusty, upstream, xenial, yakkety, zesty): ignored 6, not-affected 5, released 1.
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.
