Opera Content-Length header buffer overflow
|opera-contentlength-bo (56673)||High Risk|
Opera is vulnerable to a heap-based buffer overflow, caused by improper bounds checking when handling HTTP responses. By sending a specially-crafted HTTP response containing an overly long Content-Length header, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
Upgrade to the latest version of Opera (10.51 or later), available from the Opera Web site. See References.
