FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has security vulnerabilities; these vulnerabilities stem from incorrect packet validation, which leads to infinite recursion when parsing SCTP block parameters. This can result in stack overflows and crashes...

FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has a security vulnerability that stems from the use of select to wait for data, without verifying whether the socket descriptor is within the FDSETSIZE limit. This vulnerability may lead to stack corruption and...

FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. There is a security vulnerability in FreeBSD, which stems from the BOOTP file field not properly escaping double quotes when writing the lease file. This allows arbitrary dhclient.conf commands to be injected, potentiall...

FreeBSD : FreeBSD -- Remotely triggerable out-of-bounds heap write in dhclient (58acf4c5-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 58acf4c5-4435-11f1-bb07-bc241121aa0a advisory. As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of...

FreeBSD : FreeBSD -- Remote code execution via malicious DHCP options (9eb2533e-4434-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 9eb2533e-4434-11f1-bb07-bc241121aa0a advisory. The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing...

FreeBSD : FreeBSD -- Stack overflow via select() file descriptor set overflow (892fabf5-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 892fabf5-4435-11f1-bb07-bc241121aa0a advisory. When exchanging data over a socket, libnv uses select2 to wait for data to arrive. However, it does not...

FreeBSD : FreeBSD -- Local privilege escalation via execve() (f528ea29-4434-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f528ea29-4434-11f1-bb07-bc241121aa0a advisory. An operator precedence bug in the kernel results in a scenario where a buffer overflow causes...

FreeBSD : FreeBSD -- Heap overflow in libnv (c3a9c5a6-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the c3a9c5a6-4435-11f1-bb07-bc241121aa0a advisory. When processing the header of an incoming message, libnv failed to properly validate the message size...

FreeBSD : FreeBSD -- pf can overflow the stack parsing crafted SCTP packets (225ba563-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 225ba563-4435-11f1-bb07-bc241121aa0a advisory. Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can...

FreeBSD Security Advisory - FreeBSD-SA-26:17.libnv

FreeBSD Security Advisory - FreeBSD-SA-26:13.exec

FreeBSD Security Advisory - An operator precedence bug in the kernel results in a scenario where a buffer overflow causes attacker-controlled data to overwrite adjacent execve2 argument buffers...

PT-2026-36007

Name of the Vulnerable Software and Affected Versions FreeBSD affected versions not specified Description When processing the header of an incoming message, libnv fails to properly validate the message size. This lack of validation allows a malicious program to write outside the bounds of a heap...

PT-2026-36012

Name of the Vulnerable Software and Affected Versions FreeBSD versions prior to 15.0-RELEASE-p7 FreeBSD versions prior to 14.4-RELEASE-p3 FreeBSD versions prior to 14.3-RELEASE-p12 FreeBSD versions prior to 13.5-RELEASE-p13 FreeBSD versions from 2013 through 13.4.x Description An operator...

FreeBSD Security Advisory - FreeBSD-SA-26:15.dhclient

FreeBSD Security Advisory - As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun...

PT-2026-36009

Name of the Vulnerable Software and Affected Versions FreeBSD dhclient affected versions not specified Description The FreeBSD DHCP client fails to escape embedded double-quotes when writing the BOOTP file field to the lease file. This allows a rogue DHCP server on the same network to inject...

PT-2026-36010

Name of the Vulnerable Software and Affected Versions dhclient affected versions not specified Description When building an environment to pass to dhclient-script, the software may resize the array of string pointers. The code responsible for expanding this array incorrectly calculates the new...

FreeBSD Security Advisory - FreeBSD-SA-26:16.libnv

FreeBSD Security Advisory - When exchanging data over a socket, libnv uses select2 to wait for data to arrive. However, it does not verify whether the provided socket descriptor fits in select2's file descriptor set size limit of FDSETSIZE 1024...

PT-2026-36011

Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can eventually result in a stack overflow and panic. Remote attackers can craft packets which cause affected systems to panic. This affects any system where pf is configured to process traffic, independent...

PT-2026-36008

Name of the Vulnerable Software and Affected Versions libnv affected versions not specified Description When exchanging data over a socket, the software uses the select function to wait for data. It fails to verify if the provided socket descriptor exceeds the file descriptor set size limit of FD...
