Speex header buffer overflow

speex-header-bo (41684)

High Risk

Description:

Speex, as used in multiple products, is vulnerable to a buffer overflow, caused by improper bounds checking when processing headers. By sending a specially-crafted request via a user controlled field in the header of a hosted stream, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash..

• Canonical, Ubuntu 6.06 LTS
• Canonical, Ubuntu 7.04
• Canonical, Ubuntu 7.10
