Apache Standard Taglibs before 1.2.3 allows remote attackers to execute arbitrary code or conduct external XML entity (XXE) attacks via a crafted XSLT extension in a (1) <x:parse> or (2) <x:transform> JSTL XML tag.
Race condition in Apport before 2.17.2-0ubuntu1.1 as packaged in Ubuntu 15.04, before 2.14.70ubuntu8.5 as packaged in Ubuntu 14.10, before 2.14.1-0ubuntu3.11 as packaged in Ubuntu 14.04 LTS, and before 2.0.1-0ubuntu17.9 as packaged in Ubuntu 12.04 LTS allow local users to write to arbitrary files and gain root privileges.
The snprintf implementation in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 does not properly handle system-call errors, which allows attackers to obtain sensitive information or have other unspecified impact via unknown vectors, as demonstrated by an out-of-memory error.

Buffer overflow in the nsXMLHttpRequest::AppendToResponseText function ...
It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient.
An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS does not initialize the SYSENTER MSRs.
Please note that the Red Hat Enterprise Linux with KVM certified guest operating systems do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on KVM hypervisor.

DISPUTED Multiple integer overflows in the lzo1xdecompresssafe function in lib/lzo/lzo1xdecompresssafe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. NOTE: the author of the LZO algorithms says "the Linux kernel is not affected; media hype."
It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from the userspace via the (u)verbs API. As a result, an unrestricted physical memory access could be achieved.
A local user with access to /dev/infiniband/uverbsX could use this flaw to crash the system or, potentially, escalate their privileges on the system.
It was reported [1] that running strings, nm or objdump on a constructed PE file [2] leads to out-of bounds write to an unitialized memory area. Upstream path for this issue is at [3].

A heap overflow was reborted [1] when running objdump on a specially crafted PE executable [2]. Upstream patches that address this are at [3] and [4].

The resolveredirects function in sessions.py in requests 2.1.0 through 2.5.3 allows remote attackers to conduct session fixation attacks via a cookie without a host value in a redirect.
Use-after-free vulnerability in the mozilla::dom::IndexedDB::IDBObjectStore::CreateIndex function in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted content that is improperly handled during IndexedDB index creation.
ModelMultipleChoiceField in Django 1.6.x before 1.6.10 and 1.7.x before 1.7.3, when showhiddeninitial is set to True, allows remote attackers to cause a denial of service by submitting duplicate values, which triggers a large number of SQL queries.
The django.util.http.issafeurl function in Django before 1.4.18, 1.6.x before 1.6.10, and 1.7.x before 1.7.3 does not properly handle leading whitespaces, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted URL, related to redirect URLs, as demonstrated by a \njavascript: URL.
The django.views.static.serve view in Django before 1.4.18, 1.6.x before 1.6.10, and 1.7.x before 1.7.3 reads files an entire line at a time, which allows remote attackers to cause a denial of service (memory consumption) via a long line in a file.
The utils.http.issafeurl function in Django before 1.4.20, 1.5.x, 1.6.x before 1.6.11, 1.7.x before 1.7.7, and 1.8.x before 1.8c1 does not properly validate URLs, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a control character in a URL, as demonstrated by a \x08javascript: URL.
The utils.html.striptags function in Django 1.6.x before 1.6.11, 1.7.x before 1.7.7, and 1.8.x before 1.8c1, when using certain versions of Python, allows remote attackers to cause a denial of service (infinite loop) by increasing the length of the input string.
iconvdata/ibm930.c in GNU C Library (aka glibc) before 2.16 allows context-dependent attackers to cause a denial of service (out-of-bounds read) via a multibyte character value of "0xffff" to the iconv function when converting IBM930 encoded data to UTF-8.
Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on 64-bit systems where sizeof(sizet) is equal to 8. In the archivewritezipdata() function in libarchive/archivewritesetformatzip.c, the "s" parameter is of type sizet (64 bit, unsigned) and is cast to a 64 bit signed integer. If "s" is larger than MAXINT, it will not be set to "zip->remainingdatabytes" even though it is larger than "zip->remainingdatabytes", which leads to a buffer overflow when calling deflate().
This can lead to a segfault in an application that uses libarchive to create ZIP archives.
