CVE-2017-7745 is a vulnerability of currently unknown severity. In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the SIGCOMP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-sigcomp.c by correcting a memory-size check.. EPSS estimates a 2.46% chance of exploitation in the next 30 days.
