2) Out-of-bounds read
EUVDB-ID: #VU39362
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-8763
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The EAP-PWD module in FreeRADIUS 3.0 through 3.0.8 allows remote attackers to have unspecified impact via a crafted (1) commit or (2) confirm message, which triggers an out-of-bounds read.
