A memory exhaustion vulnerability in ISC DHCP could lead to Denial of Service.
| Package | net-misc/dhcp on all architectures |
|---|---|
| Affected versions | < 4.2.5_p1 |
| Unaffected versions | >= 4.2.5_p1 |
ISC DHCP is a Dynamic Host Configuration Protocol (DHCP) client/server.
ISC DHCP is vulnerable to a memory exhaustion attack involving regular expressions sent by DHCP clients.
A remote attacker could send a specially crafted request from a malicious or spoofed client, potentially leading to a Denial of Service condition.
There is no known workaround at this time.
All ISC DHCP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/dhcp-4.2.5_p1"
