CVE-2017-11410
In Wireshark through 2.0.13 and 2.2.x through 2.2.7, the WBXML dissector could go into an infinite loop, triggered by packet injection or a malformed capture file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Wireshark through 2.0.13 and 2.2.x through 2.2.7, the WBXML dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wbxml.c by adding validation of the relationships between indexes and lengths. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-7702.
