Description

The generic_file_splice_write function in fs/splice.c in the Linux kernel before 2.6.19 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory, a different vulnerability than CVE-2008-4210.

Affected products

Linux kernel: through 2.6.26.4; 2.2.27, 2.4.36, 2.4.36.1, 2.4.36.2, 2.4.36.3, 2.4.36.4 (+58)
