MGASA-2020-0336 - Updated python-rstlib packages fix security vulnerability

Publication date: 18 Aug 2020
URL: https://advisories.mageia.org/MGASA-2020-0336.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-14019

Open-iSCSI rtslib-fb through 2.1.72 has weak permissions for
/etc/target/saveconfig.json because shutil.copyfile (instead of shutil.copy) is
used and thus permissions are not preserved upon editing. An adversary with
prior access to /etc/target/saveconfig.json could access a later version,
resulting in a loss of integrity depending on their permission settings
(CVE-2020-14019).
