Alpine: multiple firefox-esr packages: security update to 115.3.0-r0

critical Tenable Cloud Security Plugin ID 404409

Description

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

- A compromised content process could have provided malicious data to `FilterNodeD2D1` resulting in an out-
of-bounds write, leading to a potentially exploitable crash in a privileged process. *This bug only
affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox <
118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5168)

- A compromised content process could have provided malicious data in a `PathRecording` resulting in an out-
of-bounds write, leading to a potentially exploitable crash in a privileged process. This vulnerability
affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5169)

- During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing
an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects
Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5171)

- If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently
freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. *This bug only
affects Firefox on Windows when run in non-standard configurations (such as using `runas`). Other
operating systems are unaffected.* This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and
Thunderbird < 115.3. (CVE-2023-5174)

- Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and
Thunderbird < 115.3. (CVE-2023-5176)
