Description Laura Pardo 2018-06-27 14:46:43 UTC 
A flaw was found in GIMP through 2.10.2 makes g_get_tmp_dir calls to establish temporary filenames, which may result in a filename that already exists, as demonstrated by the gimp_write_and_read_file function in app/tests/test-xcf.c. This might be leveraged by attackers to overwrite files or read file content that was intended to be private.

Created gimp tracking bugs for this issue:

Affects: fedora-all [bug 1595820]
Comment 4 Stefan Cornelius 2018-06-28 09:21:10 UTC 
Statement:

This issue did affect the versions of gimp as shipped with Red Hat Enterprise Linux 7. However, as this is an issue in a unit test, it is not a problem if you are using the precompiled gimp package. This is only a problem if you recompile gimp using the src.rpm/SPEC file. Even then it's only a problem if you do not make use of isolating build tools like mock, but instead use rpmbuild directly.
