Two new vulnerabilities have been found in the HTTP interface of monit, possibly leading to denial of service or execution of arbitrary code.
|Package||app-admin/monit on all architectures|
|Affected versions||<= 4.2|
|Unaffected versions||>= 4.2.1|
Monit is a system administration utility that allows management and monitoring of processes, files, directories and devices on a Unix system.
Monit has several vulnerabilities in its HTTP interface : a buffer overflow vulnerability in the authentication handling code and a off-by-one error in the POST method handling code.
An attacker may exploit the off-by-one error to crash the Monit daemon and create a denial of service condition, or cause a buffer overflow that would allow arbitrary code to be executed with root privileges.
A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.
Monit users should upgrade to version 4.2.1 or later:
# emerge sync # emerge -pv ">=app-admin/monit-4.2.1" # emerge ">=app-admin/monit-4.2.1"
