Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2014-1505 7 Canonical, Debian, Mozilla and 4 more 16 Ubuntu Linux, Debian Linux, Firefox and 13 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
The SVG filter implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive displacement-correlation information, and possibly bypass the Same Origin Policy and read text from a different domain, via a timing attack involving feDisplacementMap elements, a related issue to CVE-2013-1693.
CVE-2018-5154 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur while enumerating attributes during SVG animations with clip paths. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2014-1487 7 Canonical, Debian, Fedoraproject and 4 more 17 Ubuntu Linux, Debian Linux, Fedora and 14 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
