CVE-2015-3294: Oracle Solaris

Medium severity, CVSS 6.4. EPSS: 4.4% chance of exploitation in the next 30 days.

The tcp_request function in Dnsmasq before 2.73rc4 does not properly handle the return value of the setup_reply function, which allows remote attackers to read process memory and cause a denial of service (out-of-bounds read and crash) via a malformed DNS request.

Affected products

• Oracle Solaris: version 11.2 only
• Thekelleys Dnsmasq: up to and including 2.73
