Alpine: thunderbird: security update to 78.6.1-r0

high Tenable Self-Hosted Container Security Plugin ID 426813

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 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and
Firefox ESR < 78.6. (CVE-2020-35113)

- Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain
potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

- Use after free in WebRTC in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to potentially
exploit heap corruption via a crafted SCTP packet. (CVE-2020-16044)

- Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow
on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <
78.6. (CVE-2020-26971)

- Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This
could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,
and Firefox ESR < 78.6. (CVE-2020-26973)
