1 CVE-2011-2895 119 Exec Code Overflow 2011-08-19 2012-12-18
9.3
None Remote Medium Not required Complete Complete Complete
The LZW decompressor in (1) the BufCompressedFill function in fontfile/decompress.c in X.Org libXfont before 1.4.4 and (2) compress/compress.c in 4.3BSD, as used in zopen.c in OpenBSD before 3.8, FreeBSD, NetBSD 4.0.x and 5.0.x before 5.0.3 and 5.1.x before 5.1.1, FreeType 2.1.9, and other products, does not properly handle code words that are absent from the decompression table when encountered, which allows context-dependent attackers to trigger an infinite loop or a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2896.
2 CVE-2011-2393 399 DoS 2012-02-02 2012-02-03
7.8
None Remote Low Not required None None Complete
The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in FreeBSD, NetBSD, and possibly other BSD-based operating systems allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, a similar vulnerability to CVE-2010-4670.
3 CVE-2011-1074 200 Dir. Trav. +Info 2011-03-04 2011-09-21
1.9
None Local Medium Not required Partial None None
crontab.c in crontab in FreeBSD allows local users to determine the existence of arbitrary directories via a command-line argument composed of a directory name concatenated with a directory traversal sequence that leads to the /etc/crontab pathname.
4 CVE-2011-1073 59 2011-03-04 2011-09-21
1.9
None Local Medium Not required Partial None None
crontab.c in crontab in FreeBSD and Apple Mac OS X allows local users to (1) determine the existence of arbitrary files via a symlink attack on a /tmp/crontab.XXXXXXXXXX temporary file and (2) perform MD5 checksum comparisons on arbitrary pairs of files via two symlink attacks on /tmp/crontab.XXXXXXXXXX temporary files.
5 CVE-2011-0419 399 DoS 2011-05-16 2013-11-15
4.3
None Remote Medium Not required None None Partial
Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd.
6 CVE-2010-3014 200 +Info 2010-08-20 2010-08-23
1.2
None Local High Not required Partial None None
The Coda filesystem kernel module, as used in NetBSD and FreeBSD, when Coda is loaded and Venus is running with /coda mounted, allows local users to read sensitive heap memory via a large out_size value in a ViceIoctl struct to a Coda ioctl, which triggers a buffer over-read.
7 CVE-2010-2530 189 DoS 2010-09-29 2010-09-30
4.9
None Local Low Not required None None Complete
Multiple integer signedness errors in smb_subr.c in the netsmb module in the kernel in NetBSD 5.0.2 and earlier, FreeBSD, and Apple Mac OS X allow local users to cause a denial of service (panic) via a negative size value in a /dev/nsmb ioctl operation, as demonstrated by a (1) SMBIOC_LOOKUP or (2) SMBIOC_OPENSESSION ioctl call.
8 CVE-2008-4609 16 DoS 2008-10-20 2013-10-10
7.1
None Remote Medium Not required None None Complete
The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.
9 CVE-2008-2464 189 DoS 2008-09-10 2008-09-11
7.1
None Remote Medium Not required None None Complete
The mld_input function in sys/netinet6/mld6.c in the kernel in NetBSD 4.0, FreeBSD, and KAME, when INET6 is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and panic) via a malformed ICMPv6 Multicast Listener Discovery (MLD) query with a certain Maximum Response Delay value.
10 CVE-2007-3722 DoS 2007-07-12 2008-11-15
2.1
None Local Low Not required None None Partial
The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
11 CVE-2007-3721 DoS 2007-07-12 2008-11-15
2.1
None Local Low Not required None None Partial
The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
12 CVE-2006-1056 310 +Info 2006-04-20 2014-04-18
2.1
None Local Low Not required Partial None None
The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the state of floating point instructions of other processes, which can be leveraged to obtain sensitive information such as cryptographic keys. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processers in a security-relevant fashion that was not addressed by the kernels.
