FreeBSD : apache -- ap_resolve_env buffer overflow (4d49f4ba-071f-11d9-b45d-000c41e2cdad)

medium Nessus Plugin ID 36910

Synopsis

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

Description

SITIC discovered a vulnerability in Apache 2's handling of environmental variable settings in the httpd configuration files (the main `httpd.conf' and `.htaccess' files). According to a SITIC advisory :

The buffer overflow occurs when expanding ${ENVVAR} constructs in .htaccess or httpd.conf files. The function ap_resolve_env() in server/util.c copies data from environment variables to the character array tmp with strcat(3), leading to a buffer overflow.

Solution

Update the affected package.
