Description
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 configurations
• klibc project klibc (< 1.5.25)
• debian debian linux 8.0
• debian debian linux 9.0
• debian debian linux 10.0
