Alpine: thunderbird: security update to 115.5.0-r0

high Tenable Cloud Security Plugin ID 426117

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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 < 120, Firefox ESR < 115.5.0, and
Thunderbird < 115.5. (CVE-2023-6212)

- On some systems—depending on the graphics settings and drivers—it was possible to force an out-of-bounds
read and leak memory data into the images created on the canvas element. This vulnerability affects
Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. (CVE-2023-6204)

- It was possible to cause the use of a MessagePort after it had already been freed, which could potentially
have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and
Thunderbird < 115.5. (CVE-2023-6205)

- The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on
permission prompts. It was possible to use this fact to surprise users by luring them to click where the
permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR <
115.5.0, and Thunderbird < 115.5. (CVE-2023-6206)

- Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox
< 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. (CVE-2023-6207)
