Alpine: multiple firefox packages: security update to 78.0-r0

high Tenable Cloud Security Plugin ID 404369

Description

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

- Mozilla developers and community members reported memory safety bugs present in Firefox 77. 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 < 78. (CVE-2020-12426)

- During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean
Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform
electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
*Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,
but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

- When "%2F" was present in a manifest URL, Firefox's AppCache behavior may have become confused and allowed
a manifest to be served from a subdirectory. This could cause the appcache to be used to service requests
for the top level directory. This vulnerability affects Firefox < 78. (CVE-2020-12415)

- A VideoStreamEncoder may have been freed in a race condition with VideoBroadcaster::AddOrUpdateSink,
resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability
affects Firefox < 78. (CVE-2020-12416)

- Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,
resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox
on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird <
68.10.0. (CVE-2020-12417)
