Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2017-7745)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.


2) Infinite loop (CVE-ID: CVE-2017-7748)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the WSP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wsp.c by adding a length check.
