Alpine: multiple librewolf packages: security update to 74.0-r0

critical Tenable Self-Hosted Container Security Plugin ID 426478

Description

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

- Mozilla developers reported memory safety and script safety bugs present in Firefox 73. Some of these bugs
showed evidence of memory corruption or escalation of privilege and we presume that with enough effort
some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 74.
(CVE-2020-6815)

- usrsctp before 2019-12-20 has out-of-bounds reads in sctp_load_addresses_from_init. (CVE-2019-20503)

- When removing data about an origin whose tab was recently closed, a use-after-free could occur in the
Quota manager, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird <
68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6805)

- By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of
an array resized during script execution. This could have led to memory corruption and a potentially
exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and
Firefox ESR < 68.6. (CVE-2020-6806)

- When a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> task
may have been executed after the stream was destroyed, causing a use-after-free and a potentially
exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and
Firefox ESR < 68.6. (CVE-2020-6807)
