CVE-2002-0381 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-11-20 5.0 MEDIUM N/A
The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address.
CVE-2001-1559 1 Openbsd 1 Openbsd 2024-11-20 2.1 LOW 5.5 MEDIUM
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
CVE-2001-1415 1 Openbsd 1 Openbsd 2024-11-20 4.6 MEDIUM N/A
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes.
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2024-11-20 5.0 MEDIUM N/A
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.
CVE-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2024-11-20 6.2 MEDIUM N/A
fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.
CVE-2001-1047 1 Openbsd 1 Openbsd 2024-11-20 1.2 LOW N/A
Race condition in OpenBSD VFS allows local users to cause a denial of service (kernel panic) by (1) creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or (2) calling dup2 on a file descriptor in one process, then setting the descriptor to NULL via a close in another process that is created via rfork.
CVE-2001-0670 4 Bsd, Freebsd, Netbsd and 1 more 4 Bsd, Freebsd, Netbsd and 1 more 2024-11-20 7.5 HIGH N/A
Buffer overflow in BSD line printer daemon (in.lpd or lpd) in various BSD-based operating systems allows remote attackers to execute arbitrary code via an incomplete print job followed by a request to display the printer queue.
CVE-2001-0554 9 Debian, Freebsd, Ibm and 6 more 11 Debian Linux, Freebsd, Aix and 8 more 2024-11-20 10.0 HIGH N/A
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
CVE-2001-0402 3 Darren Reed, Freebsd, Openbsd 3 Ipfilter, Freebsd, Openbsd 2024-11-20 7.5 HIGH N/A
IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.
CVE-2001-0378 1 Openbsd 1 Openbsd 2024-11-20 2.1 LOW N/A
readline prior to 4.1, in OpenBSD 2.8 and earlier, creates history files with insecure permissions, which allows a local attacker to recover potentially sensitive information via readline history files.
CVE-2001-0284 1 Openbsd 1 Openbsd 2024-11-20 10.0 HIGH N/A
Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option.
CVE-2001-0268 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2024-11-20 7.2 HIGH N/A
The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address.
CVE-2001-0247 5 Freebsd, Mit, Netbsd and 2 more 5 Freebsd, Kerberos 5, Netbsd and 2 more 2024-11-20 10.0 HIGH N/A
Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
CVE-2001-0053 3 David Madore, Netbsd, Openbsd 3 Ftpd-bsd, Netbsd, Openbsd 2024-11-20 10.0 HIGH N/A
One-byte buffer overflow in replydirname function in BSD-based ftpd allows remote attackers to gain root privileges.
CVE-2000-1208 4 Immunix, Netbsd, Openbsd and 1 more 4 Immunix, Netbsd, Openbsd and 1 more 2024-11-20 7.2 HIGH N/A
Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.
CVE-2000-1010 2 Openbsd, Redhat 2 Openbsd, Linux 2024-11-20 10.0 HIGH N/A
Format string vulnerability in talkd in OpenBSD and possibly other BSD-based OSes allows remote attackers to execute arbitrary commands via a user name that contains format characters.
CVE-2000-1004 1 Openbsd 1 Openbsd 2024-11-20 4.6 MEDIUM N/A
Format string vulnerability in OpenBSD photurisd allows local users to execute arbitrary commands via a configuration file directory name that contains formatting characters.
CVE-2000-0997 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2024-11-20 7.2 HIGH N/A
Format string vulnerabilities in eeprom program in OpenBSD, NetBSD, and possibly other operating systems allows local attackers to gain root privileges.
CVE-2000-0996 1 Openbsd 1 Openbsd 2024-11-20 7.2 HIGH N/A
Format string vulnerability in OpenBSD su program (and possibly other BSD-based operating systems) allows local attackers to gain root privileges via a malformed shell.
CVE-2000-0995 1 Openbsd 1 Openbsd 2024-11-20 7.2 HIGH N/A
Format string vulnerability in OpenBSD yp_passwd program (and possibly other BSD-based operating systems) allows attackers to gain root privileges a malformed name.
