Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management errors (CVE-ID: CVE-2005-2708)
The vulnerability allows a local user to perform service disruption.
The search_binary_handler function in exec.c in Linux 2.4 kernel on 64-bit x86 architectures does not check a return code for a particular function call when virtual memory is low, which allows local users to cause a denial of service (panic), as demonstrated by running a process using the bash ulimit -v command.
Remediation
