AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Wireshark versions 2.4.0 through 2.4.11 Wireshark versions 2.6.0 through 2.6.5

Description The issue is related to a buffer overflow read in the RTSE dissector of the Wireshark network traffic analyzer, which could lead to a denial of service. This can be triggered by a remote attacker using a specially crafted trace file. The problem lies in the RTSE dissector and other ASN.1 dissectors, which could crash due to the lack of a length check in the get t61 string function.

Recommendations For Wireshark versions 2.4.0 through 2.4.11, update to a version that includes the fix for the RTSE dissector issue. For Wireshark versions 2.6.0 through 2.6.5, update to a version that includes the fix for the RTSE dissector issue. As a temporary workaround, consider disabling the RTSE dissector until a patch is available.
