Releases
Packages
- ghostscript - PostScript and PDF interpreter
Details
USN-5224-1 fixed several vulnerabilities in Ghostscript. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
It was discovered that Ghostscript incorrectly handled certain PostScript
files. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could possibly use this issue to
cause Ghostscript to crash, resulting in a denial of service, or possibly
execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
ghostscript
-
9.26~dfsg+0-0ubuntu0.16.04.14+esm1
Available with Ubuntu Pro
-
libgs9
-
9.26~dfsg+0-0ubuntu0.16.04.14+esm1
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
