Description Arvid Requate

2015-09-28 18:21:11 CEST

This security issue is fixed in upstream Debian package version 9.05~dfsg-6.3+deb7u2:

* Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write (CVE-2015-3228)

The following issues have been reported as fixed in the Debian Jessie package version (9.06~dfsg-2+deb8u3):

* Ghostscript information disclosure through getenv, filenameforall (CVE-2013-5653)
* various userparams allow %pipe% in paths, allowing remote shell command execution (CVE-2016-7976)
* .libfile doesn't check PermitFileReading array, allowing remote file disclosure (CVE-2016-7977)
* reference leak in .setdevice allows use-after-free and remote code execution (CVE-2016-7978)
* type confusion in .initialize_dsc_parser allows remote code execution (CVE-2016-7979)
* type confusion (CVE-2016-8602)
