    CVE-2015-7830

    Published: 15 Nov 2015Last Modified: 16 Apr 2026

    Summary:

    Details: 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.
