In NetworkManager 0.9.2.0, when a new wireless network was created with WPA/WPA2 security in AdHoc mode, it created an open/insecure network.
Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: MyISAM ). Supported versions that are affected are 5.5.53 and earlier, 5.6.34 and earlier and 5.7.16 and earlier. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data.

Integer underflow in the cupsRasterReadPixels function in filter/raster.c in CUPS before 2.0.2 allows remote attackers to have unspecified impact via a malformed compressed raster file, which triggers a buffer overflow.
bdf/bdflib.c in FreeType before 2.5.4 identifies property names by only verifying that an initial substring is present, which allows remote attackers to discover heap pointer values and bypass the ASLR protection mechanism via a crafted BDF font.
Array index error in the parsefond function in base/ftmac.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (out-of-bounds read) or obtain sensitive information from process memory via a crafted FOND resource in a Mac font file.
Integer signedness error in the MacReadPOSTResource function in base/ftobjs.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font.
Multiple integer signedness errors in the pcfgetencodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row.
sfnt/ttload.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting the values, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted SFNT table.
Multiple integer overflows in sfnt/ttcmap.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (out-of-bounds read or memory corruption) or possibly have unspecified other impact via a crafted cmap SFNT table.
FreeType before 2.5.4 does not check for the end of the data during certain parsing actions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted Type42 font, related to type42/t42parse.c and type1/t1load.c.
Off-by-one error in the pcfgetproperties function in pcf/pcfread.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PCF file with a 0xffffffff size value that is improperly incremented.
The ttsbitdecoderinit function in sfnt/ttsbit.c in FreeType before 2.5.4 proceeds with a count-to-size association without restricting the count value, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted embedded bitmap.
unzip 6.0 allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) via an extra field with an uncompressed size smaller than the compressed field size in a zip archive that advertises STORED method compression.
It was reported [1] that under high load, getaddrinfo() starts sending DNS queries to random file descriptors, e.g. some unrelated socket connected to a remote service.

Unspecified vulnerability in the Java SE, Java SE Embedded, JRockit component in Oracle Java SE 5.0u75, 6u85, 7u72, and 8u25; Java SE Embedded 7u71 and 8u6; and JRockit R27.8.4 and R28.3.4 allows remote attackers to affect availability via unknown vectors related to Security.
It was reported [1] that the Linux kernel suffered from a flaw when doing key garbage collection. The patch [1] describes the issue as:
""" When a key is being garbage collected, it's key->user would get put before the ->destroy() callback is called, where the key is removed from it's respective tracking structures.
This leaves a key hanging in a semi-invalid state which leaves a window open for a different task to try an access key->user. An example is findkeyringbyname() which would dereference key->user for a key that is in the process of being garbage collected (where key->user was freed but ->destroy() wasn't called yet - so it's still present in the linked list).
"""
An unprivileged local user could use this flaw to crash the system.

Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata.
ppa.py in Software Properties before 0.81.13.3 does not validate the server certificate when downloading PPA GPG key fingerprints, which allows man-in-the-middle (MITM) attackers to spoof GPG keys for a package repository.

It is unexpected and not allowed to call TTY buffer helpers like ttyinsertflipstring concurrently. This may lead to crashes when ECHOing is enabled and concurrect writers call ptywrite in the meantime. In that case the two writers: the ECHOing from a workqueue and ptywrite from the process race and can overflow the corresponding TTY buffer.
An unprivileged local user could use this flaw to crash the system or, potentially, escalate their privileges on the system.

Directory traversal vulnerability in the unpacking functionality in dpkg before 1.15.9, 1.16.x before 1.16.13, and 1.17.x before 1.17.8 allows remote attackers to write arbitrary files via a crafted source package, related to "C-style filename quoting."
DistUpgrade/DistUpgradeFetcherCore.py in Update Manager before 1:0.87.31.1, 1:0.134.x before 1:0.134.11.1, 1:0.142.x before 1:0.142.23.1, 1:0.150.x before 1:0.150.5.1, and 1:0.152.x before 1:0.152.25.5 on Ubuntu 8.04 through 11.10 does not verify the GPG signature before extracting an upgrade tarball, which allows man-in-the-middle attackers to (1) create or overwrite arbitrary files via a directory traversal attack using a crafted tar file, or (2) bypass authentication via a crafted meta-release file.
Untrusted search path vulnerability in pammotd (aka the MOTD module) in libpam-modules before 1.1.3-2ubuntu2.1 on Ubuntu 11.10, before 1.1.2-2ubuntu8.4 on Ubuntu 11.04, before 1.1.1-4ubuntu2.4 on Ubuntu 10.10, before 1.1.1-2ubuntu5.4 on Ubuntu 10.04 LTS, and before 0.99.7.1-5ubuntu6.5 on Ubuntu 8.04 LTS, when using certain configurations such as "session optional pammotd.so", allows local users to gain privileges by modifying the PATH environment variable to reference a malicious command, as demonstrated via uname.
An array index bounds overrun flaw has been discovered in the vmxnet3 device as emulated by qemu.
A privileged guest user could use this flaw to corrupt qemu process' memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.

This issue was discovered by Michael S. Tsirkin of Red Hat.
It was discovered that ICC profiles were not parsed correctly. An untrusted Java application or applet could possibly use this flaw to cause a denial of service.
It was discovered that JAXP the CharInfo object did not properly prevent access to arbitrary files when a SecurityManager is present. An untrusted Java application or applet could possibly use this flaw to disclose sensitive information.
It was discovered that the JNDI DNS client did not properly randomize the DNS query ID. A remote attacker could exploit this flaw to e.g. perfom DNS spoofing attacks.
It was discovered that the Security component in OpenJDK could leak some timing information when preforming PKCS#1 unpadding. This could possibly lead to disclosure of some information meant to be protected by encryption.
This fix improves the fix for CVE-2014-0411 (bug 1053010) applied via via Oracle CPU January 2014.
Martin Holst Swende discovered a flaw in the way modheaders handled chunked requests. A remote attacker could use this flaw to bypass intended modheaders restrictions, allowing them to send requests to applications that include headers that should have been removed by modheaders.
Discussion and a possible patch is available from the following thread:

The davxmlgetcdata function in main/util.c in the moddav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request.
