Updated hylafax+ packages fix security vulnerabilitiesPublication date: 31 Aug 2020
Affected Mageia releases : 7
CVE: CVE-2020-15396 , CVE-2020-15397
In HylaFAX+ through 7.0.2, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root (CVE-2020-15396). HylaFAX+ through 7.0.2 has scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user calling these binaries (often root) (CVE-2020-15397). The hylafax+ package has been updated to version 7.0.3, fixing thesee issues and several other bugs.
