ISC BIND contains a data processing errors vulnerability that could allow remote attackers to cause a denial of service via TKEY queries.
Buffer overflow vulnerabilities in functions pnggetPLTE/pngsetPLTE, allowing remote attackers to cause DoS to application or have unspecified other impact. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bitdepth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.
Affected versions of libpng are before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19.

ProFTPD contains an improper access control vulnerability that could allow remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.
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.
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.

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.
A flaw in libjpeg-turbo was reported [1],[2],[3] that could lead to a local denial of service when processing a specially-crafted JPEG issue.
One of the reports indicate that this only affects versions of libjpeg-turbo prior to 1.3.1 due to 1.3.1 rejecting the malformed image due to duplicate SOI markers.
Upstream has fixes for this issue [4],[5]. Also refer to the upstream bug [6].

Heap-based buffer overflow in PolarSSL 1.x before 1.2.17 and ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long hostname to the server name indication (SNI) extension, which is not properly handled when creating a ClientHello message. NOTE: this identifier has been SPLIT per ADT3 due to different affected version ranges. See CVE-2015-8036 for the session ticket issue that was introduced in 1.3.0.
Heap-based buffer overflow in ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long session ticket name to the session ticket extension, which is not properly handled when creating a ClientHello message to resume a session. NOTE: this identifier was SPLIT from CVE-2015-5291 per ADT3 due to different affected version ranges.
Bodo Möller, Thai Duong and Krzysztof Kotowicz of Google discovered a flaw in the design of SSL version 3.0 that would allow an attacker to calculate the plaintext of secure connections, allowing, for example, secure HTTP cookies to be stolen.

Integer underflow in the LCodeGen::PrepareKeyedOperand function in arm/lithium-codegen-arm.cc in Google V8 before 3.25.28.16, as used in Google Chrome before 35.0.1916.114, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger a negative key value.

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.
