Description

This security bulletin contains information about 1 vulnerability.


1) Improper Neutralization of Special Elements in Output Used by a Downstream Component (CVE-ID: CVE-2017-7703)

CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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 IMAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-imap.c by calculating a line's end correctly.
