Package : ghostscript
CVE ID : CVE-2019-14811 CVE-2019-14812 CVE-2019-14813 CVE-2019-14817
It was discovered that various procedures in Ghostscript, the GPL
PostScript/PDF interpreter, do not properly restrict privileged calls,
which could result in bypass of file system restrictions of the dSAFER
sandbox.
For the oldstable distribution (stretch), these problems have been fixed
in version 9.26a~dfsg-0+deb9u5.
For the stable distribution (buster), these problems have been fixed in
version 9.27~dfsg-2+deb10u2.
We recommend that you upgrade your ghostscript packages.
For the detailed security status of ghostscript please refer to its
security tracker page at:
