The updated packages fix security vulnerabilities:
There is a floating point exception in the kodakradcloadraw function in dcrawcommon.cpp in LibRaw 0.18.2. It will lead to a remote denial of service attack. (CVE-2017-13735)
In LibRaw through 0.18.4, an out of bounds read flaw related to kodak65000loadraw has been reported in dcraw/dcraw.c and internal/ dcrawcommon.cpp. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash. (CVE-2017-14608)
A stack-based buffer overflow in the find_green() function of dcraw through 9.28, as used in ufraw-batch and many other products, may allow a remote attacker to cause a control-flow hijack, denial-of-service, or unspecified other impact via a maliciously crafted raw photo file. (CVE-2018-19655)
