MyDNS update.c buffer overflow
|mydns-update-bo (33933)||Medium Risk|
MyDNS is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the update.c file. If allow-update is enabled, an authenticated remote attacker with update privileges could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
Apply the appropriate patch for your system. See References.
