Name of the Vulnerable Software and Affected Versions Sun Solaris versions 8 through 10 OpenSolaris versions prior to snv 103

Description The issue arises from improper handling of interaction between the filesystem and virtual-memory implementations. This allows local users to cause a denial of service, resulting in a deadlock and system halt, by performing specific operations on the same file, involving mmap and write operations.

Recommendations For Sun Solaris versions 8 through 10, consider applying configuration changes to restrict access to sensitive files and minimize the risk of exploitation. For OpenSolaris versions prior to snv 103, update to a version after snv 103 to resolve the issue. As a temporary workaround, consider restricting the use of mmap and write operations on the same file to minimize the risk of deadlock and system halt.
