This security bulletin contains information about 1 security vulnerability.
1) Security restrictions bypass (CVE-ID: CVE-2005-3273)
The vulnerability allows a remote non-authenticated attacker to corrupt data.
The rose_rt_ioctl function in rose_route.c for Radionet Open Source Environment (ROSE) in Linux 2.6 kernels before 2.6.12, and 2.4 before 2.4.29, does not properly verify the ndigis argument for a new route, which allows attackers to trigger array out-of-bounds errors with a large number of digipeats.
