Description Laura Pardo 2018-12-21 17:55:20 UTC 
LibRaw is vulnerable to a denial of service, caused by a flaw in the parse_sinar_ia function in internal/dcraw_common.cpp. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause a denial of service condition.

Comment 3 Riccardo Schirone 2019-01-03 10:31:32 UTC 
Function parse_sinar_ia() execute a loop for X times, where X is read from the file and is not properly checked. By providing a very large number (or a negative one) it is possible to execute the loop many time and waste resources.
