Summary
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).
