Updated php packages fix security vulnerability

Publication date: 31 Oct 2021
Modification date: 31 Oct 2021
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-21703

Description

Updated php packages fix security vulnerability:

In PHP versions 8.0.x below 8.0.12, when running PHP FPM SAPI with main
FPM daemon process running as root and child worker processes running as
lower-privileged users, it is possible for the child processes to access
memory shared with the main process and write to it, modifying it in a
way that would cause the root process to conduct invalid memory reads and
writes, which can be used to escalate privileges from local unprivileged
user to the root user (CVE-2021-21703).

The php packages have been updated to 8.0.12 that fixes this issue and
other bugs.
