Description:
Thomas Walpuski has reported a vulnerability in l2tpd, which potentially can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the "write_packet()" function. This can be exploited to cause a BSS-based (Block Storage Segment) buffer overflow by faking a L2TP tunnel establishment and then sending a specially crafted packet.
Successful exploitation may crash the application or potentially allow execution of arbitrary code. However, this has not been proven.
The vulnerability has been reported in all current versions.
