Alpine: multiple firefox packages: security update to 82.0-r0

critical Tenable Self-Hosted Container Security Plugin ID 404373

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 81. 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 < 82. (CVE-2020-15684)

- Crossbeam is a set of tools for concurrent programming. In crossbeam-channel before version 0.4.4, the
bounded channel incorrectly assumes that `Vec::from_iter` has allocated capacity that same as the number
of iterator elements. `Vec::from_iter` does not actually guarantee that and may allocate extra memory. The
destructor of the `bounded` channel reconstructs `Vec` from the raw pointer based on the incorrect assumes
described above. This is unsound and causing deallocation with the incorrect capacity when
`Vec::from_iter` has allocated different sizes with the number of iterator elements. This has been fixed
in crossbeam-channel 0.4.4. (CVE-2020-15254)

- If a valid external protocol handler was referenced in an image tag, the resulting broken image size could
be distinguished from a broken image size of a non-existent protocol handler. This allowed an attacker to
successfully probe whether an external protocol handler was registered. This vulnerability affects Firefox
< 82. (CVE-2020-15680)

- When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM
thread could have overwritten another's entry in a shared stub table, resulting in a potentially
exploitable crash. This vulnerability affects Firefox < 82. (CVE-2020-15681)

- When a link to an external protocol was clicked, a prompt was presented that allowed the user to choose
what application to open it in. An attacker could induce that prompt to be associated with an origin they
didn't control, resulting in a spoofing attack. This was fixed by changing external protocol prompts to be
tab-modal while also ensuring they could not be incorrectly associated with a different origin. This
vulnerability affects Firefox < 82. (CVE-2020-15682)
