FFmpeg 2.x allows remote attackers to conduct cross-origin attacks and read arbitrary files by using the subfile protocol in an HTTP Live Streaming (HLS) M3U8 file, leading to an external HTTP request in which the URL string contains an arbitrary line of a local file.
libavcodec/tiff.c in FFmpeg before 2.8.6 does not properly validate RowsPerStrip values and YCbCr chrominance subsampling factors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted TIFF file, related to the tiffdecodetag and decodeframe functions.
FFmpeg 2.x allows remote attackers to conduct cross-origin attacks and read arbitrary files by using the concat protocol in an HTTP Live Streaming (HLS) M3U8 file, leading to an external HTTP request in which the URL string contains the first line of a local file.
The movreaddref function in libavformat/mov.c in Libav before 11.7 and FFmpeg before 0.11 allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via the entries value in a dref box in an MP4 file.
SQL injection vulnerability in libraries/centralcolumns.lib.php in phpMyAdmin 4.4.x before 4.4.15.7 and 4.6.x before 4.6.3 allows remote attackers to execute arbitrary SQL commands via a crafted database name that is mishandled in a central column query.
Dominic Scheirlinck of VendHQ reports:
Many software projects and vendors have implemented support for the “Proxy” request header in their respective CGI implementations and languages by creating the “HTTPPROXY” environmental variable based on the header value. When this variable is used (in many cases automatically by various HTTP client libraries) any outgoing requests generated in turn from the attackers original request can be redirected to an attacker controlled proxy. This allows attackers to view potentially sensitive information, reply with malformed data, or to hold connections open causing a potential denial of service.
The PHP web framework contains will automatically populate the HTTPPROXY environmental variable with a user supplied "Proxy" header.
The OneLine32 function in io-ico.c in gdk-pixbuf before 2.35.3 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via crafted dimensions in an ICO file.
An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application.
The AliasHandler component in PostfixAdmin before 3.0.2 allows remote authenticated domain admins to delete protected aliases via the delete parameter to delete.php, involving a missing permission check.

Heap-based buffer overflow in the EscapeParenthesis function in GraphicsMagick before 1.3.25 allows remote attackers to have unspecified impact via unknown vectors.
The TIFFGetField function in coders/tiff.c in GraphicsMagick 1.3.24 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a file containing an "unterminated" string.
The gitoidnfmt function in commit.c in libgit2 before 0.24.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via a cat-file command with a crafted object file.
The Utah RLE reader in GraphicsMagick before 1.3.25 allows remote attackers to cause a denial of service (CPU consumption or large memory allocations) via vectors involving the header information and the file size.
The checkallocations function in libass/assshaper.c in libass before 0.13.4 allows remote attackers to cause a denial of service (memory allocation failure) via unspecified vectors.
An unsigned overflow leading to heap buffer overflow vulnerability was found in GraphicsMagick 8BIM reader. A maliciously crafted file could cause the application to crash.

Integer overflow in the getnum function in luastruct.c in Redis 2.8.x before 2.8.24 and 3.0.x before 3.0.6 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow.
Multiple buffer overflows in GraphicsMagick 1.3.23 allow remote attackers to cause a denial of service (crash) via a crafted SVG file, related to the (1) TracePoint function in magick/render.c, (2) GetToken function in magick/utility.c, and (3) GetTransformTokens function in coders/svg.c.
The idnatoascii4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via 64 bytes of input.

A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client.
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.
