Description Quality Assurance univentionstaff 2018-08-09 10:17:45 CEST
New Debian ghostscript 9.06~dfsg-2+deb8u7 fixes:
This update addresses the following issue(s):
* 
* The fill_threshhold_buffer function in base/gxht_thresh.c in Artifex Software, Inc. Ghostscript 9.20 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. (CVE-2016-10317)
* The set_text_distance function in devices/vector/gdevpdts.c in the pdfwrite component in Artifex Ghostscript through 9.22 does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document. (CVE-2018-10194)
CVE_2018-11645 is open

9.06~dfsg-2+deb8u7 (Sun, 29 Apr 2018 11:58:34 +0200) * Non-maintainer upload. * Segfault with fuzzing file in gxht_thresh_image_init * Buffer overflow in fill_threshold_buffer (CVE-2016-10317) * pdfwrite - Guard against trying to output an infinite number (CVE-2018-10194)
* CVE-2016-10317 ghostscript: Heap-buffer overflow in the fill_threshold_buffer function (CVE-2016-10317)
* CVE-2018-10194 ghostscript: Stack-based out-of-bounds write in pdf_set_text_matrix function in gdevpdts.c (CVE-2018-10194)
