  1. MediumCVSS 5.0 EPSS 4.0%

    The supersede_lease function in memory.c in ISC DHCP (dhcpd) server 2.0pl5 allows remote attackers to cause a denial of service (application crash) via a DHCPDISCOVER packet with a 32 byte client-identifier, which causes the packet to be interpreted as a corrupt uid and causes th...

  2. MediumCVSS 5.0 EPSS 8.0%

    ISC dhcrelay (dhcp-relay) 3.0rc9 and earlier, and possibly other versions, allows remote attackers to cause a denial of service (packet storm) via a certain BOOTP packet that is forwarded to a broadcast MAC address, causing an infinite loop that is not restricted by a hop count.

  3. HighCVSS 10.0 EPSS 16.8%

    The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable...

  4. HighCVSS 10.0 EPSS 45.3%

    Buffer overflow in the logging capability for the DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13 allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via multiple hostname options in (1) DISCOVER, (2) OFFER, (3) REQUEST...

  5. HighCVSS 7.5 EPSS 18.9%

    Multiple stack-based buffer overflows in the error handling routines of the minires library, as used in the NSUPDATE capability for ISC DHCPD 3.0 through 3.0.1RC10, allow remote attackers to execute arbitrary code via a DHCP message containing a long hostname.

  6. HighCVSS 10.0 EPSS 31.1% Public exploit

    Format string vulnerabilities in the logging routines for dynamic DNS code (print.c) of ISC DHCP daemon (DHCPD) 3 to 3.0.1rc8, with the NSUPDATE option enabled, allow remote malicious DNS servers to execute arbitrary code via format strings in a DNS server response.
