Description Adam Mariš 2017-03-16 13:03:10 UTC

The parse_string_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

Comment 1 Adam Mariš 2017-03-16 13:27:51 UTC

Created libplist tracking bugs for this issue:

Affects: fedora-all [bug 1432971]

Comment 3 Peter Robinson 2017-05-12 14:28:41 UTC

Why are you reopening these?

Comment 4 Tomas Hoger 2017-05-12 20:18:01 UTC

These CVE bugs filed against the "Security Response" product are used to track flaws across multiple products using Red Hat Bugzilla.  While Fedora was dealt with, there are other products with pending actions.  Also Fixed-In field has special meaning / format in the "Security Response" bugs.

Where is the details of the "special meaning" publicly documented?

Nowhere right now. But since the bug is not assigned to you (only the tracking one is), it is not really expected that you'd need to update it. The changes you made here should have been done in the product-relevant bug only.
