Alpine: firefox-esr: security update to 68.6.1-r0 (deprecated)

critical Tenable Cloud Security Plugin ID 400380

Description

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

- When reading from areas partially or fully outside the source resource with WebGL's
<code>copyTexSubImage</code> method, the specification requires the returned values be zero. Previously,
this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability
affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6821)

- On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in
<code>GMPDecodeData</code>. It is possible that with enough effort this could have been exploited to run
arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
(CVE-2020-6822)

- Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs
present in Firefox 74 and Firefox ESR 68.6. 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 Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6825)
