CVE-2017-7960
A heap-based buffer over-read vulnerability could be triggered remotely via a crafted CSS file to cause a denial of service.
CVE-2017-7961
An ‘outside the range of representable values of type long’ undefined behavior issue was found in libcroco, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted CSS file.
For Debian 7 ‘Wheezy’, these problems have been fixed in version 0.6.6-2+deb7u1.
We recommend that you upgrade your libcroco packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
