Moved to Bug 24107.
Comment 5 Shlomi Fish 2019-01-02 14:57:14 CET
dcraw-9.26.0-1.1 was submitted to mga6 core/updates testing.
Comment 6 David Walser 2019-01-02 15:12:32 CET

Updated dcraw packages fix security vulnerability:

A NULL pointer dereference flaw was found in the way dcraw processed images. An
attacker could potentially use this flaw to crash dcraw by tricking it into
processing crafted images (CVE-2018-5801).


Updated packages in core/updates_testing:

from dcraw-9.27.0-1.1.mga6.src.rpm
