Amazon Linux 2 Security Advisory: ALAS-2023-2248
Advisory Release Date: 2023-09-13 23:44 Pacific
Advisory Updated Date: 2023-09-20 19:40 Pacific
Severity: Important

Issue Overview:

Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension. This vulnerability affects Thunderbird < 115.0.1. (CVE-2023-3417)

Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. 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. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4056)

Memory safety bug (CVE-2023-4584)
