Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU4138
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2016-8704
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the process_bin_append_prepend() function due to integer overflow. A remote attacker can send specially crafted Memcached binary protocol commands, trigger heap-based buffer overflow and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
net-misc/memcached to version: 1.4.33
Gentoo Linux: All versions
