Description Arvid Requate univentionstaff 2017-10-30 17:32:25 CET
Upstream Debian package version 9.06~dfsg-2+deb8u6 fixes:

* The Ins_MIRP function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document. (CVE-2017-9611)
* The Ins_IP function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact via a crafted document. (CVE-2017-9612)
* The Ins_MDRP function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document. (CVE-2017-9726)
* The gx_ttfReader__Read function in base/gxttfb.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document. (CVE-2017-9727)
* The Ins_JMPR function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document. (CVE-2017-9739)
* The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c. (CVE-2017-9835)
* psi/ztoken.c in Artifex Ghostscript 9.21 mishandles references to the scanner state structure, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document, related to an out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c. (CVE-2017-11714)
