The issue is fixed in 26.1.8. No e...

EUVD-2026-29290

barebox prior to version 2026.04.0 contains an out-of-bounds read vulnerability in DHCP option parsing within the dhcpmessagetype function that fails to verify the options pointer remains within received packet bounds. An attacker on the same broadcast domain can send a crafted DHCP Offer or ACK...

CVE-2026-34960

barebox before 2026.04.0 contains an out-of-bounds read in DHCP option parsing (dhcp_message_type) due to not ensuring the options pointer stays within packet bounds. An attacker on the same broadcast domain can send a crafted DHCP Offer/ACK lacking a proper 0xff end marker to cause the parser to...

Wireshark 2.0.x < 2.0.13 Multiple Vulnerabilities (macOS)

The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.0.13. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.0.13 advisory. - In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the RGMP dissector could crash. This was addressed i...

CVE-2026-42511

The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing injection of arbitrary dhclient.conf directives. When the lease file is subsequently re-parsed by dhclient, e.g., after a system restart, an attacker-controlled field from the lease is passed to...
