This seems to affect 0.15.x branch only, we ship only 0.14.x currently. Can you verify?
This has been assigned CVE-2013-2127 as per: http://www.openwall.com/lists/oss-security/2013/05/29/7
This one I cannot tell by looking at the code whether or not we are affected. I'm going to email upstream and ask.
According to upstream, 0.14.x is not affected by this flaw: "0.14.x are not affected by 'buffer overrun' (this is not arbitrary access in 0.15 , but access to lookup table at fixed index [(unsigned)(-1)] ) The code calculating max real data value is completely different in 0.14 (and early 0.15 alphas), so no prior initialization of data maximum to -1." Since we only ship 0.14.x, this does not affect Fedora at all.
Digikam embeds 0.15.0.beta3 and this patch applies to it, so it needs to be updated.
