Hi Julien I was wondering whether I should open a pu bug myself. Thank you. I do support your proposal.
I believe we should also include one, possibily two patches from jessie: 1) http://patch-tracker.debian.org/patch/series/view/mdbtools/0.7-2/binaries_to_string fixes important bug #713826 that got me a RC critical bug and a jessie-ignore tag. This is about a missing break within a switch/case, resulting in next case block being run, and resulting in a SEGV. This only occur when you have binary in your MDB file. This is a one-line patch adding the missing break; This one has been repported on other distros, and upstream. I would really like to have it fixed. 2) http://patch-tracker.debian.org/patch/series/view/mdbtools/0.7-2/gmdb2_double_free is a more rare bug, but it also results in SEGV. This also is a oneliner fix: gmdb_debug_add_item frees the str parameter. The line patched was properly calling g_strdup_printf, but discards the results, resulting in str beeing uninitialized (same value has previous call), as thus beeing freed twice. So attached my proposal. I'm not sure the 2) above qualify for a proposed update. This is a SEGV, but only in the debug window few people will open, and it has no security impact. Please advise.
