Description Andrej Nemec 2018-12-06 09:58:41 UTC 
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.

Comment 1 Stefan Cornelius 2018-12-13 09:40:32 UTC 
In RHEL versions this function has stack canaries, which makes this significantly harder to exploit.
