DATE CVE VULNERABILITY TITLE RISK
2009-09-18 CVE-2009-3238 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in multiple products
The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."

5.5
2009-08-11 CVE-2009-2416 Use After Free vulnerability in multiple products
Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
6.5
2009-07-30 CVE-2009-2408 Improper Certificate Validation vulnerability in multiple products
Mozilla Network Security Services (NSS) before 3.12.3, Firefox before 3.0.13, Thunderbird before 2.0.0.23, and SeaMonkey before 1.1.18 do not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

2009-06-08 CVE-2009-1961 Improper Locking vulnerability in multiple products
The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions.

4.7
2008-11-13 CVE-2008-4989 Improper Certificate Validation vulnerability in multiple products
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN).
5.9
2008-09-04 CVE-2007-6716 fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test.

5.5
2008-08-27 CVE-2008-3281 XML Entity Expansion vulnerability in multiple products
libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
6.5
2008-08-12 CVE-2008-3275 Classic Buffer Overflow vulnerability in multiple products
The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.

2006-12-29 CVE-2006-6811 Reachable Assertion vulnerability in multiple products
KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference.

2005-09-30 CVE-2005-3106 Improper Locking vulnerability in multiple products
Race condition in Linux 2.6, when threads are sharing memory mapping via CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a denial of service (deadlock) by triggering a core dump while waiting for a thread that has just performed an exec.
