Debian DSA-4686-1 : apache-log4j1.2 - security update

critical Nessus Plugin ID 136675
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


It was discovered that the SocketServer class included in apache-log4j1.2, a logging library for java, is vulnerable to deserialization of untrusted data. An attacker can take advantage of this flaw to execute arbitrary code in the context of the logger application by sending a specially crafted log event.


Upgrade the apache-log4j1.2 packages.

For the oldstable distribution (stretch), this problem has been fixed in version 1.2.17-7+deb9u1.

For the stable distribution (buster), this problem has been fixed in version 1.2.17-8+deb10u1.
