Package : ghostscript
Version : 9.26a~dfsg-0+deb8u6
CVE ID : CVE-2019-14869
Manfred Paul and Lukas Schauer reported that the .charkeys procedure in
Ghostscript, the GPL PostScript/PDF interpreter, does not properly
restrict privileged calls, which could result in bypass of file system
restrictions of the dSAFER sandbox.
For Debian 8 "Jessie", this problem has been fixed in version
9.26a~dfsg-0+deb8u6.
We recommend that you upgrade your ghostscript packages.
