CVE-2016-8706
HighSummary
An integer overflow in the process_bin_sasl_auth function in Memcached can be exploited to cause heap overflow and lead to remote code execution.
Risk Assessment
Exploitation of this vulnerability could allow an attacker to remotely execute code on the Memcached server, posing a significant security risk.
Recommendation
It is recommended to update Memcached to the latest version to mitigate this vulnerability and to monitor logs for potential attack attempts.
Other vulnerabilities in Memcached
See all- CVE-2017-9951High
The try_read_command function in memcached before version 1.4.39 allows remote attackers to cause a denial of service (segmentation fault) via a request to add/set a key, which makes a comparison between signed and unsigned int and triggers a heap-based buffer over-read.
- CVE-2016-8705Critical
Multiple integer overflows in the process_bin_update function in Memcached can be exploited to cause heap overflow and lead to remote code execution.
- CVE-2016-8704Critical
An integer overflow in the process_bin_append_prepend function in Memcached can be exploited to cause heap overflow and lead to remote code execution.
- CVE-2026-47784High
Memcached before version 1.6.42 uses the memcmp function for password comparison in SASL authentication, causing a timing side-channel vulnerability. An attacker can read passwords by measuring response times.
- CVE-2026-47783High
In memcached before version 1.6.42, username data for SASL password database authentication has a timing side channel because a loop exits as soon as a valid username is found by sasl_server_userdb_checkpass.
Original NVD description (English source)
An integer overflow in process_bin_sasl_auth function in Memcached, which is responsible for authentication commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.
