Description
This security bulletin contains information about 1 security vulnerability.
1) Security restrictions bypass (CVE-ID: CVE-2010-1146)
The vulnerability allows a local user to execute arbitrary code.
The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.
Remediation
Install update from vendor's website.
