SUSE CVE-2016-8602

The .sethalftone5 function in psi/zht2.c in Ghostscript before 9.21 allows remote attackers to cause a denial of service application crash or possibly execute arbitrary code via a crafted Postscript document that calls .sethalftone5 with an empty operand stack...

NewStart CGSL CORE 5.04 / MAIN 5.04 : ghostscript Multiple Vulnerabilities (NS-SA-2019-0054)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ghostscript packages installed that are affected by multiple vulnerabilities: - It was discovered that the ghostscript PDF14 compositor did not properly handle the copying of a device. An attacker could possibly exploit thi...

ghostscript: subroutines within pseudo-operators must themselves be pseudo-operators (700317)

It was found that ghostscript 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 outside of the SAFER...

Ghostscript 9.26 - Pseudo-Operator Remote Code Execution Exploit

Ghostscript 9.26 - Pseudo-Operator Remote Code Execution Exploit I noticed ghostscript 9.26 was released, so had a quick look and spotted some errors. For background, this is how you define a subroutine in postscript: /hello hello\n print def That's simple enough, but because a subroutine is just...

Ghostscript 9.26 - Pseudo-Operator Remote Code Execution

I noticed ghostscript 9.26 was released, so had a quick look and spotted some errors. For background, this is how you define a subroutine in postscript: /hello hello\n print def That's simple enough, but because a subroutine is just an executable array of commands, you need to mark it as...

ghostscript: corruption of operand stack

It was found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection...
