Description
This security bulletin contains information about 1 security vulnerability.
1) Improper locking (CVE-ID: CVE-2005-0529)
The vulnerability allows a local user to gain access to sensitive information.
Linux kernel 2.6.10 and 2.6.11rc1-bk6 uses different size types for offset arguments to the proc_file_read and locks_read_proc functions, which leads to a heap-based buffer overflow when a signed comparison causes negative integers to be used in a positive context.
Remediation
Install update from vendor's website.
