In klibc 1.5.20 and 1.5.21, the DHCP options written by ipconfig to /tmp/net-$DEVICE.conf are not properly escaped. This may allow a remote attacker to send a specially crafted DHCP reply which could execute arbitrary code with the privileges of any process which sources DHCP options.

Affected Software

Name Vendor Start Version End Version
Klibc Klibc_project * 1.5.25 (excluding)
Klibc Ubuntu hardy *
Klibc Ubuntu lucid *
Klibc Ubuntu maverick *
