The remote host is affected by the vulnerability described in GLSA-200703-16 (Apache JK Tomcat Connector: Remote execution of arbitrary code)
ZDI reported an unsafe memory copy in mod_jk that was discovered by an anonymous researcher in the map_uri_to_worker function of native/common/jk_uri_worker_map.c .
Impact :
A remote attacker can send a long URL request to an Apache server using Tomcat. That can trigger the vulnerability and lead to a stack-based buffer overflow, which could result in the execution of arbitrary code with the permissions of the Apache user.
Workaround :
There is no known workaround at this time.
