The remote host is affected by the vulnerability described in GLSA-200411-03 (Apache 1.3: Buffer overflow vulnerability in mod_include)
A possible buffer overflow exists in the get_tag() function of mod_include.c. Impact
If Server Side Includes (SSI) are enabled, a local attacker may be able to run arbitrary code with the rights of an httpd child process by making use of a specially-crafted document with malformed SSI. Workaround
There is no known workaround at this time.
All Apache users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/apache-1.3.32-r1"
