Descriptions

Stack-based buffer overflow in the munge_other_line function in cachemgr.cgi in the squid package before 3.1.23-16.el6_8.6 in Red Hat Enterprise Linux 6 allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-4051.

Desbordamiento de búfer basado en pila en la función munge_other_line en cachemgr.cgi en el paquete squid en versiones anteriores a 3.1.23-16.el6_8.6 en Red Hat Enterprise Linux 6 permite a atacantes remotos ejecutar código arbitrario a través de vectores no especificados. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2016-4051.

It was found that the fix for CVE-2016-4051 released via RHSA-2016:1138 did not properly prevent the stack overflow in the munge_other_line() function. A remote attacker could send specially crafted data to the Squid proxy, which would exploit the cachemgr CGI utility, possibly triggering execution of arbitrary code.
