Alpine: multiple patch packages: security update to 2.7.6-r6

high Tenable Self-Hosted Container Security Plugin ID 424328

Description

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

- do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character.
NOTE: this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated
to a shell metacharacter. (CVE-2018-20969)

- GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files,
specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to
be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's
CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.
(CVE-2018-1000156)

- GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a
crafted patch file that contains an ed style diff payload with shell metacharacters. The ed editor does
not need to be present on the vulnerable system. This is different from CVE-2018-1000156. (CVE-2019-13638)
