MGASA-2019-0236 - Updated ghostscript packages fix security vulnerability

Publication date: 31 Aug 2019
URL: https://advisories.mageia.org/MGASA-2019-0236.html
Type: security
Affected Mageia releases: 6, 7
CVE: CVE-2019-10216

Updated ghostscript packages fix security vulnerability:

It was found that the .buildfont1 procedure did not properly secure its
privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An
attacker could abuse this flaw by creating a specially crafted PostScript
file that could escalate privileges and access files outside of restricted
areas (CVE-2019-10216).

Also, the Mageia 7 update fixes a bounding box issue that affects
klatexformula (mga#24866).
