Vulnerability Note VU#967236

Original Release Date: 2007-01-31 | Last Revised: 2007-02-07


Sun Solaris fails to properly handle ICMP packets, which may allow a remote, unauthenticated attacker to cause a denial of service.


Sun Solaris 10 contains an unspecified error that can cause a system panic when handling a specially crafted ICMP packet. Note that Solaris 8 and 9 are not affected by this issue.


A remote, unauthenticated attacker may be able to create a denial-of-service condition by causing a system panic on a vulnerable Sun Solaris system.
