The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks.
Multiple buffer overflows in plugins/imageformats/ico/qicohandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and possibly execute arbitrary code via a crafted ICO image.

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.
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.

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.
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.
Integer overflow in oggenc in vorbis-tools 1.4.0 allows remote attackers to cause a denial of service (crash) via a crafted number of channels in a WAV file, which triggers an out-of-bounds memory access.
oggenc in vorbis-tools 1.4.0 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a WAV file with the number of channels set to zero.
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.

A denial of service flaw was found in the way the HSLFSlideShow class implementation in Apache POI handled certain PPT files. A remote attacker could submit a specially crafted PPT file that would cause Apache POI to hang indefinitely.

Upstream Fix:
https://svn.apache.org/viewvc?view=revision&revision=1643680
I discovered a flaw in Zarafa WebAccess >= 7.0.0 and Zarafa WebApp (any version) that could allow a remote unauthenticated attacker to exhaust the disk space of /tmp. Depending on the setup /tmp might be on / (e.g. RHEL). Zarafa WebApp is a fork and the successor of the Zarafa WebAccess.
The affected files are /usr/share/zarafa-webaccess/senddocument.php as well as /usr/share/zarafa-webapp/senddocument.php. The default upload size is 30 MB (via /etc/httpd/conf.d/zarafa-webaccess.conf / zarafa-webapp.conf).
I do not know if $tmpname is predictable (for race conditions) but likely not. The 2nd parameter is only a prefix according to the PHP documentation of tempnam().
From my point of view the file "senddocument.php" is neither referenced nor used anywhere in the code and could be simply removed.
Upstream has been notified and I am awaiting their response. At the moment this RHBZ is only meant to have this tracked somewhere, please do not yet disclose.
MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session.
As per the upstream advisory:
OpenSSL TLS clients enabling anonymous ECDH ciphersuites are subject to a denial of service attack.
OpenSSL 1.0.0 users should upgrade to 1.0.0m. OpenSSL 1.0.1 users should upgrade to 1.0.1h.

As per the upstream advisory:
A buffer overrun attack can be triggered by sending invalid DTLS fragments to an OpenSSL DTLS client or server. This is potentially exploitable to run arbitrary code on a vulnerable client or server.
Only applications using OpenSSL as a DTLS client or server affected.
OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h.

As per the upstream advisory:
By sending an invalid DTLS handshake to an OpenSSL DTLS client, the code can be made to recurse, eventually crashing in a DoS attack.
Only applications using OpenSSL as a DTLS client are affected.
OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m. OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h. .

The Frontend in Zabbix before 1.8.20rc2, 2.0.x before 2.0.11rc2, and 2.2.x before 2.2.2rc1 allows remote "Zabbix Admin" users to modify the media of arbitrary users via unspecified vectors.

The dossl3write function in s3pkt.c in OpenSSL 1.x through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.
Heap-based buffer overflow in the readu32 function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG image.
