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.
An issue was discovered in klibc before 2.0.9. Multiple possible integer overflows in the cpio command on 32-bit systems may result in a buffer overflow or other security impact.
