[ASA-201901-18] ghostscript: sandbox escape
Arch Linux Security Advisory ASA-201901-18 ========================================== Severity: High Date : 2019-01-29 CVE-ID : CVE-2019-6116 Package : ghostscript Type : sandbox escape Remote : Yes Link : https://security.archlinux.org/AVG-860 Summary ======= The package <a href="/package/ghostscript">ghostscript</a> before version 9.26-2 is vulnerable to sandbox escape. Resolution ========== Upgrade to 9.26-2. # pacman -Syu "ghostscript>=9.26-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== It was found that <a href="/package/ghostscript">ghostscript</a> could leak sensitive operators on the operand stack when a pseudo-operator pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER protection in order to, for example, have access to the file system and execute commands. Impact ====== A remote attacker is able to escape the sandbox via a specially crafted PostScript document.
