Description Laura Pardo 2018-07-27 21:40:57 UTC

A flaw was found in Exiv2 0.26. The samples/geotag.cpp in the example code misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.

Comment 1 Laura Pardo 2018-07-27 21:41:30 UTC

Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1609397]

Comment 3 Stefan Cornelius 2018-07-30 09:32:09 UTC

We don't ship this. Additionally, this is should not be a problem for us, as we use glibc and realpath() should allocate the buffer there.

Comment 4 Stefan Cornelius 2018-07-30 09:32:17 UTC

Statement:

This issue did not affect the versions of exiv2 as shipped with Red Hat Enterprise Linux 6 and 7.
