CVE-2015-5315: Debian Linux

Medium severity, CVSS 5.9. EPSS: 2.5% chance of exploitation in the next 30 days.

The eap_pwd_process function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when EAP-pwd is enabled in a network configuration profile, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.

Affected products

• Debian Debian Linux: version 8.0 only
• w1.fi Wpa Supplicant: from 2.0, before 2.6 (fixed in 2.6)
