CVE Reference(s):

Description


A security issue has been discovered in Ghostscript, which can potentially be exploited by malicious people to bypass certain security restrictions and compromise a user's system.

The security issue is caused due to the application reading certain postscript files in the current working directory although the "-P-" command line option is set. This can be exploited to execute arbitrary postscript commands e.g. via the "gs_init.ps" file, if a user is tricked into opening a file using the "-P-" option in an attacker controlled directory.

The security issue is confirmed in version 8.71. Other versions may also be affected.


Solution:
Fixed in the subversion repository.

Provided and/or discovered by:
Christopher Yeleighton. Additional information by Paul Szabo.
