Description Arvid Requate univentionstaff 2017-09-08 10:42:51 CEST
Upstream Debian package version 0.14.6-2+deb7u2 fixes:

* An error within the "parse_tiff_ifd()" function (internal/dcraw_common.cpp) in LibRaw versions before 0.18.2 can be exploited to corrupt memory. (CVE-2017-6886)

* A boundary error within the "parse_tiff_ifd()" function (internal/dcraw_common.cpp) in LibRaw versions before 0.18.2 can be exploited to cause a memory corruption via e.g. a specially crafted KDC file with model set to "DSLR-A100" and containing multiple sequences of 0x100 and 0x14A TAGs. (CVE-2017-6887)
