Descriptions

liblber/io.c in OpenLDAP 2.2.4 to 2.4.10 allows remote attackers to cause a denial of service (program termination) via crafted ASN.1 BER datagrams that trigger an assertion error.

El archivo liblber/io.c en OpenLDAP versiones 2.2.4 hasta 2.4.10, permite a los atacantes remotos causar una denegación de servicio (finalización del programa) por medio de datagramas ASN.1 BER diseñados que desencadenan un error de aserción.

This vulnerability allows remote attackers to deny services on vulnerable installations of OpenLDAP. Authentication is not required to exploit this vulnerability.
The specific flaw exists in the decoding of ASN.1 BER network datagrams. When the size of a BerElement is specified incorrectly, the application will trigger an assert(), leading to abnormal program termination.
