Technical 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.

Remediation

Check the references section for vendor advisories and patches from oracle. Update solaris to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
