Software Description: - perl: Practical Extraction and Report Language Details: USN-4602-1 fixed several vulnerabilities in Perl. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM. Original advisory details: ManhND discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-10543) Hugo van der Sanden and Slaven Rezic discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-10878) Sergey Aleynikov discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-12723) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: perl 5.18.2-2ubuntu1.7+esm3 Ubuntu 12.04 ESM: perl 5.14.2-6ubuntu2.11 In general, a standard system update will make all the necessary changes. Description: Security Fix(es): * Addressed a security issue which can allow a malicious playbook author to elevate to the awx user from outside the isolated environment: CVE-2021-20253 * Upgraded to a more recent version of Django to address CVE-2021-3281. * Upgraded to a more recent version of autobahn to address CVE-2020-35678. For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * Upgraded to the latest oVirt inventory plugin to resolve a number of inventory syncing issues that can occur on RHEL7. * Upgraded to the latest theforeman.foreman inventory plugin to resolve a few bugs and performance regressions. * Fixed several issues related to how Tower rotates its log files. * Fixed a bug which can prevent Tower from installing on RHEL8 with certain non-en_US.UTF-8 locales. * Fixed a bug which can cause unanticipated delays in certain playbook output. * Fixed a bug which can cause job runs to fail for playbooks that print certain types of raw binary data. * Fixed a bug which can cause unnecessary records in the Activity Stream when Automation Analytics data is collected. * Fixed a bug which can cause Tower PostgreSQL backups to fail when a non-default PostgreSQL username is specified. * Fixed a bug which can intermittently cause access to encrypted Tower settings to fail, resulting in failed job launches. * Fixed a bug which can cause certain long-running jobs running on isolated nodes to unexpectedly fail.
