CVSS v3.1 |
| FreeBSD kernel 4.6 and earlier closes the file descriptors 0, 1, and 2 after they have already been assigned to /dev/null when the descriptors reference procfs or linprocfs, which could allow local users to reuse the file descriptors in a setuid or setgid program to modify critical data and gain privileges. |
| FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce. |
| Local users can start Sendmail in daemon mode and gain root privileges. |
| The accept_filter mechanism in FreeBSD 4 through 4.5 does not properly remove entries from the incomplete listen queue when adding a syncache, which allows remote attackers to cause a denial of service (network service availability) via a large number of connection attempts, which fills the queue. |
| Buffer overflow in FreeBSD libmytinfo library allows local users to execute commands via a long TERMCAP environmental variable. |
| Local user gains root privileges via buffer overflow in rdist, via lookup() function. |
| Kerberos 5 su (k5su) in FreeBSD 4.5 and earlier does not verify that a user is a member of the wheel group before granting superuser privileges, which could allow unauthorized users to execute commands as root. |
| The kernel in FreeBSD 3.2 follows symbolic links when it creates core dump files, which allows local attackers to modify arbitrary files. |
| Kerberos 5 su (k5su) in FreeBSD 4.4 and earlier relies on the getlogin system call to determine if the user running k5su is root, which could allow a root-initiated process to regain its privileges after it has dropped them. |
| KDE klock allows local users to kill arbitrary processes by specifying an arbitrary PID in the .kss.pid file. |
| ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges. |
| IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors. |
| The rc system startup script for FreeBSD 4 through 4.5 allows local users to delete arbitrary files via a symlink attack on X Windows lock files. |
| KDE allows local users to execute arbitrary commands by setting the KDEDIR environmental variable to modify the search path that KDE uses to locate its executables. |
| Buffer overflow in the huh program in the orville-write package allows local users to gain root privileges. |
| NetBSD 1.4.2 and earlier allows remote attackers to cause a denial of service by sending a packet with an unaligned IP timestamp option. |
| Integer overflow in the Berkeley Fast File System (FFS) in FreeBSD 4.6.1 RELEASE-p4 and earlier allows local users to access arbitrary file contents within FFS to gain privileges by creating a file that is larger than allowed by the virtual memory system. |
| Sendmail allows local users to write to a file and gain group permissions via a .forward or :include: file. |
| Memory leak in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (memory exhaustion) via ICMP echo packets that trigger a bug in ip_output() in which the reference count for a routing table entry is not decremented, which prevents the entry from being removed. |
| FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files. |
