PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument load method, (2) the xmlwriteropenuri function, (3) the finfofile function, or (4) the hashhmacfile function, as demonstrated by a filename\0.xml attack that bypasses an intended configuration in which client users may read only .xml files.

PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read arbitrary files via crafted input to an application that calls the streamresolveincludepath function in ext/standard/streamsfuncs.c, as demonstrated by a filename\0.extension attack that bypasses an intended configuration in which client users may read files with only one specific extension.

Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote authenticated users to affect availability via vectors related to GIS.

The bufferslowrealign function in HAProxy 1.5.x before 1.5.14 and 1.6-dev does not properly realign a buffer that is used for pending outgoing data, which allows remote attackers to obtain sensitive information (uninitialized memory contents of previous requests) via a crafted request.

The dosoapcall function in ext/soap/soap.c in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 does not verify that the uri property is a string, which allows remote attackers to obtain sensitive information by providing crafted serialized data with an int data type, related to a "type confusion" issue.

The pharparsetarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive.

Algorithmic complexity vulnerability in the multipartbufferheaders function in main/rfc1867.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 allows remote attackers to cause a denial of service (CPU consumption) via crafted form data that triggers an improper order-of-growth outcome.

The phphandler function in sapi/apache2handler/sapiapache2.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, when the Apache HTTP Server 2.4.x is used, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via pipelined HTTP requests that result in a "deconfigured interpreter."

ext/phar/phar.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (buffer over-read and application crash) via a crafted length value in conjunction with crafted serialized data in a phar archive, related to the pharparsemetadata and pharparsepharfile functions.

Due converting PIO to the new memory read/write api we no longer provide separate I/O region lenghts for read and write operations. As a result, reading from PIT Mode/Command register will end with accessing pit->channels with invalid index and potentially cause memory corruption and/or minor information leak.

A privileged guest user in a guest with QEMU PIT emulation enabled could potentially (tough unlikely) use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. (QEMU part of the vulnerability)

A privileged guest user in a guest could potentially (tough unlikely) use this flaw to execute arbitrary code on the host. (KVM part of the vulnerability)

An issue was discovered in the linux kernel's tty subsystem handling during shutdown. The flaw was possible to take a reference to the ldisc during shutdown phase.

This race occurs on hangup of tty. It races and hangs on ldsemdownwrite on a semaphore that is being aquired by a new reader(CPU 1). The new reader/writer is sleeping in ldsemdownread() and the hangup is sleeping in ldsemdownwrite().

It was discovered that the java-1.8.0-openjdk packages for Red Hat Enterprise Linux released via RHSA-2015:0809 (https://rhn.redhat.com/errata/RHSA-2015-0809.html) regressed the fix for the CVE-2015-0383 (bug 1123870) issue - "OpenJDK: insecure hsperfdata temporary file handling (Hotspot, 8050807)". This regression makes it possible to exploit the original issue and allow local attacker to make other users of OpenJDK 8 packages to overwrite arbitrary file via a symlink attack. Refer to bug 1123870 for technical details.

daemon/abrt-handle-upload.in in Automatic Bug Reporting Tool (ABRT), when moving problem reports from /var/spool/abrt-upload, allows local users to write to arbitrary files or possibly have other unspecified impact via a symlink attack on (1) /var/spool/abrt or (2) /var/tmp/abrt.

The moveuploadedfile implementation in ext/standard/basicfunctions.c in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 truncates a pathname upon encountering a \x00 character, which allows remote attackers to bypass intended extension restrictions and create files with unexpected names via a crafted second argument. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243.
