A vulnerability in lxccontainer, ansible module, was found allowing to get root inside the container. The problem is in the createscript function, which tries to write to /opt/.lxc-attach-script inside of the container. If the attacker can write to /opt/.lxc-attach-script before that, he can overwrite arbitrary files or execute commands as root.
The certrevoke command in FreeIPA does not check for the "revoke certificate" permission, which allows remote authenticated users to revoke arbitrary certificates by leveraging the "retrieve certificate" permission.
Bug description
OCaml versions 4.02.3 and earlier have a runtime bug that, on 64-bit platforms, causes sizes arguments to an internal memmove call to be sign-extended from 32 to 64-bits before being passed to the memmove function.
This leads arguments between 2GiB and 4GiB to be interpreted as larger than they are (specifically, a bit below 2^64), causing a buffer overflow.
Arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak.
This commit fixes the bug: https://github.com/ocaml/ocaml/commit/659615c7b100a89eafe6253e7a5b9d84d0e8df74#diff-a97df53e3ebc59bb457191b496c90762 The function camlbitstring is called indirectly from such functions as String.copy. String.copy for instance is supposed to be a "safe" function for which OCaml's memory safety guarantees apply.
Potential SQL injection in ORDER and GROUP statements of ZendDbSelect
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.
Buffer overflow in the calccoeff function in libass/assblur.c in libass before 0.13.4 allows remote attackers to cause a denial of service via unspecified vectors.

slock allows attackers to bypass the screen lock via vectors involving an invalid password hash, which triggers a NULL pointer dereference and crash.
Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWEDHOSTS.
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.
Django 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3 use a hardcoded password for a temporary database user created when running tests with an Oracle database, which makes it easier for remote attackers to obtain access to the database server by leveraging failure to manually specify a password in the database settings TEST dictionary.
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.
Heap-based buffer overflow in the parsepacket function in network.c in collectd before 5.4.3 and 5.x before 5.5.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted network packet.
A use-after-free vulnerability in libcurl was found. libcurl works with easy handles using the type 'CURL ' that are objects the application creates using curleasyinit(). They are the handles that are all each associated with a single transfer at a time. libcurl also has an internal struct that represents and holds most state that is related to a single connection. An easy handle can hold references to one or many such connection structs depending on the requested operations.
When using libcurl's multi interface, an application performs transfers by adding one or more easy handles to the multi handle and then it can drive all those transfers in parallel.
Due to a flaw, libcurl could leave a pointer to a freed connection struct dangling in an easy handle that was previously added to a multi handle when curlmulticleanup() is called with an easy handle still added to it. This does not seem to cause any notable harm if the handle is then closed properly.
However, if the easy handle would instead get used again with the easy interface and curleasyperform() to do another transfer, it would blindly use the connection struct pointer now pointing to freed memory.
An application could be made to allocate its own fake version of the connect struct, fill in some data and then have the curleasyperform() call do something that clearly was not intended by the original code.

A race condition was found in the way Linux kernel's memory subsystem handled breakage of the read only private mappings COW situation on write access.
An unprivileged local user could use this flaw to gain write access to otherwise read only memory mappings and thus increase their privileges on the system.

The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries.

tiffttopnm in netpbm 10.47.63 does not properly use the libtiff TIFFRGBAImageGet function, which allows remote attackers to cause a denial of service (out-of-bounds read and write) via a crafted tiff image file, related to transposing width and height values.
