Description

The pcapng_read_if_descr_block function in wiretap/pcapng.c in the pcapng parser in Wireshark 1.12.x before 1.12.8 uses too many levels of pointer indirection, which allows remote attackers to cause a denial of service (incorrect free and application crash) via a crafted packet that triggers interface-filter copying.

Wireshark Foundation Wireshark: 1.12.0, 1.12.1, 1.12.2, 1.12.3, 1.12.4, 1.12.5 (+2)
