The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.Show less

Certain "programming errors" in the msync system call for FreeBSD 5.2.1 and earlier, and 4.10 and earlier, do not properly handle the MS_INVALIDATE operation, which leads to cache consistency problems that allow a local user to prevent certain changes to files from being committed to disk.Show less

The jail_attach system call in FreeBSD 5.1 and 5.2 changes the directory of a calling process even if the process doesn't have permission to change directory, which allows local users to gain read/write privileges to files and directories within another jail.Show less

FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.Show less

The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.Show less

mksnap_ffs in FreeBSD 5.1 and 5.2 only sets the snapshot flag when creating a snapshot for a file system, which causes default values for other flags to be used, possibly disabling security-critical settings and allowing a local user to bypass intended access restrictions.Show less

The TCP MSS (maximum segment size) functionality in netinet allows remote attackers to cause a denial of service (resource exhaustion) via (1) a low MTU, which causes a large number of small packets to be produced, or (2) via a large number of packets with a small TCP payload, which cause a large number of calls to the resource-intensive sowakeup function.Show less

Integer overflow in the f_count counter in FreeBSD before 4.2 through 5.0 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via multiple calls to (1) fpathconf and (2) lseek, which do not properly decrement f_count through a call to fdrop.Show less

The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.Show less

The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.Show less

Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.Show less

Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.Show less

Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.Show less
