The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.
The following packages have been upgraded to a later upstream version: ghostscript (9.27). (BZ#1874523)
Security Fix(es):
ghostscript: use-after-free vulnerability in igc_reloc_struct_ptr() could result in DoS (CVE-2020-14373)
ghostscript: buffer overflow in lprn_is_black() in contrib/lips4/gdevlprn.c could result in a DoS (CVE-2020-16287)
ghostscript: buffer overflow in pj_common_print_page() in devices/gdevpjet.c could result in a DoS (CVE-2020-16288)
ghostscript: buffer overflow in jetp3852_print_page() in devices/gdev3852.c could result in a DoS (CVE-2020-16290)
ghostscript: buffer overflow in contrib/gdevdj9.c could result in a DoS (CVE-2020-16291)
ghostscript: buffer overflow in mj_raster_cmd() in contrib/japanese/gdevmjc.c could result in a DoS (CVE-2020-16292)
ghostscript: NULL pointer dereference in compose_group_nonknockout_nonblend_isolated_allmask_common() in base/gxblend.c could result in a DoS (CVE-2020-16293)
ghostscript: buffer overflow in epsc_print_page() in devices/gdevepsc.c could result in a DoS (CVE-2020-16294)
ghostscript: NULL pointer dereference in clj_media_size() in devices/gdevclj.c could result in a DoS (CVE-2020-16295)
