1) Security restrictions bypass

EUVDB-ID: #VU95760

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-3273

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's repository.
