ISC BIND inet_network buffer overflow
| iscbind-inetnetwork-bo (39670) |  High Risk |
Description:
ISC BIND is vulnerable to an off-by-one buffer overflow, caused by improper bounds checking by the inet_network() function. By sending a specially-crafted argument, a remote attacker could overflow a buffer and execute arbitrary code or cause the system to crash.
Platforms Affected:
- FreeBSD, FreeBSD 6.2
- ISC, BIND 8
- ISC, BIND 9.0
- ISC, BIND 9.1
- ISC, BIND 9.2.0
- ISC, BIND 9.3.0
- ISC, BIND 9.3.1
- ISC, BIND 9.3.2
- ISC, BIND 9.3.3
- ISC, BIND 9.3.4
- ISC, BIND 9.4.0
- ISC, BIND 9.4.1
- ISC, BIND 9.4.2
- ISC, BIND 9.5.0a1
- ISC, BIND 9.5.0a2
- ISC, BIND 9.5.0a3
- ISC, BIND 9.5.0a4
- ISC, BIND 9.5.0a5
- ISC, BIND 9.5.0a6
- ISC, BIND 9.5.0a7
- ISC, BIND 9.5.0b1
- RedHat, Enterprise Linux 5
- RedHat, Enterprise Linux 5 Client
- RedHat, Enterprise Linux 5 Client Workstation
- Sun, Solaris 10 SPARC
