Comment 1 Laura Pardo 2018-09-04 22:16:40 UTC
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1625432]

Comment 2 Riccardo Schirone 2018-09-18 12:01:05 UTC
Statement:

This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include the vulnerable code.

Comment 4 Riccardo Schirone 2018-09-18 12:47:19 UTC
ParseImageResourceBlocks function in coders/psd.c does not check if the the read value plus the base `p` buffer may overflow. Thus a big `count` value can bypass the check and result in an out-of-bound read later on during the execution of the function.
