CVE-2020-25866

Опубликовано: 23 сент. 2020
Источник: redhat
CVSS3: 7.5

Описание

In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs.

Отчет

Wireshark as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8 is not affected because the versions shipped do not contain the BLIP dissector.
