Alpine: multiple firefox-esr packages: security update to 115.6.0-r0

high Tenable Cloud Security Plugin ID 408231

Description

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

- Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 ESR < 115.6, Thunderbird < 115.6, and
Firefox < 121. (CVE-2023-6864)

- The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems
with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and sandbox
escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
(CVE-2023-6856)

- When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller
than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS).
Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox <
121. (CVE-2023-6857)

- Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling.
This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6858)

- A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability
affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6859)
