Network Audio System USL socket buffer overflow
| nas-uslsocket-bo (33047) |  High Risk |
Description:
Network Audio System is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the accept_att_local() function. By sending specially-crafted data using the USL socket, a local attacker could overflow a buffer and execute arbitrary code on the system with ROOT privileges.
Platforms Affected:
- Canonical, Ubuntu 5.10
- Canonical, Ubuntu 6.06 LTS
- Canonical, Ubuntu 6.10
- Debian, Debian Linux 3.1
- Gentoo, Linux
- MandrakeSoft, Mandrake Linux 2007 X86_64
- MandrakeSoft, Mandrake Linux 2007
- Network Audio System, Network Audio System 1.8a and prior
