Alpine: multiple librewolf packages: security update to 85.0-r0

high Tenable Self-Hosted Container Security Plugin ID 426999

Description

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

- Mozilla developers reported memory safety bugs present in Firefox 84. 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 < 85. (CVE-2021-23965)

- Using the new logical assignment operators in a JavaScript switch statement could have caused a type
confusion, leading to a memory corruption and a potentially exploitable crash. This vulnerability affects
Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. (CVE-2021-23954)

- The browser could have been confused into transferring a pointer lock state into another tab, which could
have lead to clickjacking attacks. This vulnerability affects Firefox < 85. (CVE-2021-23955)

- An ambiguous file picker design could have confused users who intended to select and upload a single file
into uploading a whole directory. This was addressed by adding a new prompt. This vulnerability affects
Firefox < 85. (CVE-2021-23956)

- Navigations through the Android-specific `intent` URL scheme could have been misused to escape iframe
sandbox. Note: This issue only affected Firefox for Android. Other operating systems are unaffected. This
vulnerability affects Firefox < 85. (CVE-2021-23957)
