Descriptions

Memory safety bugs present in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6.

The Mozilla Foundation Security Advisory describes this flaw as: Memory safety bugs present in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Cornel Ionce discovered that Firefox did not properly manage memory when opening the print preview dialog. An attacker could potentially exploit this issue to cause a denial of service.
