Overview

CVE-2015-6242 is a medium-severity vulnerability affecting oracle solaris. It was published on August 24, 2015 and has a CVSS 2.0 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The wmem_block_split_free_chunk function in epan/wmem/wmem_allocator_block.c in the wmem block allocator in the memory manager in Wireshark 1.12.x before 1.12.7 does not properly consider a certain case of multiple realloc operations that restore a memory chunk to its original size, which allows remote attackers to cause a denial of service (incorrect free operation and application crash) via a crafted packet.

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.
