The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket.
It was found that espfix funcionality (when returning to userspace with a 16 bit stack, the CPU will not restore the high word of esp for us on executing iret and thus potentially leaks kernel addresses; espfix fixes this) does not work for 32-bit KVM paravirt guests.
A local unprivileged user could potentially use this flaw to leak kernel stack addresses.

Race condition in the Mozilla Maintenance Service in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Windows allows local users to write to arbitrary files and consequently gain privileges via vectors involving a hard link to a log file during an update.
D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 allows local users to (1) cause a denial of service (prevention of new connections and connection drop) by queuing the maximum number of file descriptors or (2) cause a denial of service (disconnect) via multiple messages that combine to have more than the allowed number of file descriptors for a single sendmsg call.
QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004.
acroread in Adobe Acrobat Reader 8.1.2 allows local users to overwrite arbitrary files via a symlink attack on temporary files related to SSL certificate handling.
Quote from http://patchwork.ozlabs.org/patch/35412/: Commit 9ef1d4c7c7aca1cd436612b6ca785b726ffb8ed8 introduced a typo in initialization.
arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x8664 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.
epan/dissectors/packet-nfs.c in the NFS dissector in Wireshark 1.4.x before 1.4.14, 1.6.x before 1.6.9, and 1.8.x before 1.8.1 allows remote attackers to cause a denial of service (loop and CPU consumption) via a crafted packet.
GnuPG before 1.4.14, and Libgcrypt before 1.5.3 as used in GnuPG 2.0.x and possibly other products, allows local users to obtain private RSA keys via a cache side-channel attack involving the L3 cache, aka Flush+Reload.
Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.31 and earlier and 5.6.11 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server Replication.
A denial of service flaw was found in the way UNIX system D-BUS format string wrapper implementation of D-BUS, a system for sending messages between applications, used to measure the length of the provided format string and its arguments in certain circumstances. A remote attacker could supply a specially-crafted input to an application / service, utilizing the services / functionality of the libdbus library that, when processed would lead to that application / service crash.

A security flaw was found in the way Clutter, an open source software library for creating rich graphical user interfaces, used to manage translation of hierarchy events in certain circumstances (when underlying device disappeared, causing XIQueryDevice query to throw an error). Physically proximate attackers could use this flaw for example to obtain unauthorized access to gnome-shell session right after system resume (due to gnome-shell crash).

A buffer overflow flaw was reported [1] in libsrtp, Cisco's reference implementation of the Secure Real-time Transport Protocol (SRTP), in how the cryptopolicysetfromprofileforrtp() function applies cryptographic profiles to an srtppolicy. This could allow for a crash of a client linked against libsrtp (like asterisk or linphone).
A pull request in git [2] has a patch to correct this issue.

According to the upstream security report [1] the following flaw was found in OpenVPN 2.3.0 and earlier:
OpenVPN 2.3.0 and earlier running in UDP mode are subject to chosen ciphertext injection due to a non-constant-time HMAC comparison function. Plaintext recovery may be possible using a padding oracle attack on the CBC mode cipher implementation of the crypto library, optimistically at a rate of about one character per 3 hours. PolarSSL seems vulnerable to such an attack; the vulnerability of OpenSSL has not been verified or tested.
OpenVPN servers are typically configured to silently drop packets with the wrong HMAC. For this reason measuring the processing time of the packets is not trivial without a MITM position. In practice, the attack likely needs some target-specific information to be effective.
The severity of this vulnerability can be considered low. Only if OpenVPN is configured to use a null-cipher, arbitrary plain-text can be injected which can completely open up this attack vector.
A fix has been committed to git [2]; this is corrected in OpenVPN 2.3.1 and later.

It was found that Subversion's moddavsvn Apache HTTPD server module will use excessive amounts of memory when a large number of properties are set or deleted on a node. This can lead to a DoS.
Setting or deleting a large number of properties on a node (file or directory) will result in a large amount of memory use. Due to the memory pooling behavior of Apache httpd and Subversion the completion of the request will not result in the immediate release of memory used. Repeated commits with the same properties will result in each httpd process plateauing out at some amount of memory. This could result in a Denial of Service if the system is exhausted of all available memory.

Unspecified vulnerability in the VirtualBox component in Oracle Virtualization 4.0, 4.1, and 4.2 allows local users to affect integrity and availability via unknown vectors related to Core. NOTE: The previous information was obtained from the January 2013 Oracle CPU. Oracle has not commented on claims from another vendor that this issue is related to an incorrect comparison in the vgadrawtext function in Devices/Graphics/DevVGA.cpp, which can cause VirtualBox to "draw more lines than necessary."
Agostino Sarubbo reported on the oss-security mailing list [1] that, on Gentoo, thttpd log file is world-readable. This could allow an unprivileged user to read the log file.

arch/x86/x86emulate/x86emulate.c in Xen 3.2.1 through 4.4.x does not properly check privileges, which allows local HVM guest users to gain privileges or cause a denial of service (crash) via a crafted (1) CALL, (2) JMP, (3) RETF, (4) LCALL, (5) LJMP, or (6) LRET far branch instruction.
The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemudriver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors.

The krb5ldapgetpasswordpolicyfromdn function in plugins/kdb/ldap/libkdbldap/ldappwdpolicy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.
libvirt 1.0.0 through 1.2.x before 1.2.5, when fine grained access control is enabled, allows local users to read arbitrary files via a crafted XML document containing an XML external entity declaration in conjunction with an entity reference to the (1) virDomainDefineXML, (2) virNetworkCreateXML, (3) virNetworkDefineXML, (4) virStoragePoolCreateXML, (5) virStoragePoolDefineXML, (6) virStorageVolCreateXML, (7) virDomainCreateXML, (8) virNodeDeviceCreateXML, (9) virInterfaceDefineXML, (10) virStorageVolCreateXMLFrom, (11) virConnectDomainXMLFromNative, (12) virConnectDomainXMLToNative, (13) virSecretDefineXML, (14) virNWFilterDefineXML, (15) virDomainSnapshotCreateXML, (16) virDomainSaveImageDefineXML, (17) virDomainCreateXMLWithFiles, (18) virConnectCompareCPU, or (19) virConnectBaselineCPU API method, related to an XML External Entity (XXE) issue.

The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections, which allows local users to cause a denial of service (incomplete connection consumption and prevention of new connections) via a large number of incomplete connections.
D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 does not properly close connections for processes that have terminated, which allows local users to cause a denial of service via a D-bus message containing a D-Bus connection file descriptor.
