Alpine: ruby-addressable: security update to 2.8.0-r0

high Tenable Cloud Security Plugin ID 407004

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard
 library. An uncontrolled resource consumption vulnerability exists after version 2.3.0 through version
 2.7.0. Within the URI template implementation in Addressable, a maliciously crafted template may result in
 uncontrolled resource consumption, leading to denial of service when matched against a URI. In typical
 usage, templates would not normally be read from untrusted user input, but nonetheless, no previous
 security advisory for Addressable has cautioned against doing this. Users of the parsing capabilities in
 Addressable but not the URI template capabilities are unaffected. The vulnerability is patched in version
 2.8.0. As a workaround, only create Template objects from trusted sources that have been validated not to
 produce catastrophic backtracking. (CVE-2021-32740)
