It was discovered that the Kerberos implementation in the Security component of OpenJDK used RSA-MD5 checksum in Ticket Granting Service (TGS) requests even though MD5 algorithm is no longer considered safe for such use case. A remote attacker could possibly use this flaw to manipulate TGS requests.
A flaw was found in the URL class implementation in the Networking component of OpenJDK. An incorrect check to determine if a URLStreamHandler is builtin or not can lead to incorrect URL normalization in certain cases.
A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel.
A flaw was found in the implementation of Intel Transactional Synchronization Extensions (TSX) abortion where a local authenticated attacker with the ability to monitor execution time is able to infer TSX memory state by comparing abort execution times.
This could allow information disclosure via this observed sidechannel for any TSX transaction being executed while an attacker is able to observe abort timing.

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization).
It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire).
As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks.
A flaw was found in computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.
This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition

It was discovered that the mysqldsafe could read ledir value - which specifies the directory where mysqld is stored - from configuration file. This could allow a user with privileges to write to some mysql configuration file - either mysql OS user, or any local OS user able to write to the config via some other way, e.g. by exploiting CVE-2016-6662 - to escalate their privileges to root if mysqldsafe was run with root privileges.
This problem is related to this change applied as part of the CVE-2016-6662 fix:
https://github.com/mysql/mysql-server/commit/684a165f28b3718160a3e4c5ebd18a465d85e97c#diff-144aa2f11374843c969d96b7b84247eaR211
It introduced restriction that mysqld and mysqldversion options can only be specified on the command line and can not be defined in a configuration file. However, such restriction was trivial to bypass while ledir was not restricted in a similar way.
Restriction for ledir was added in MySQL versions 5.5.54, 5.6.35, and 5.7.17. The following related entry can be found in the release notes:
The --ledir option now is accepted only on the command line, not in option files.

The CVE was made public via Oracle CPU January 2017:

Multiple cases of insecure use of chmod and chown were found in the MySQL init script:
- In database directory initialization code: https://github.com/mysql/mysql-server/blob/mysql-5.6.34/packaging/rpm-oel/mysql.init#L97
- In code handling error log file creation and permission setting: https://github.com/mysql/mysql-server/blob/mysql-5.6.34/packaging/rpm-oel/mysql.init#L73
The mysql OS user could use these flaws to escalate privileges to root.
Note that the second issue is only exploitable in configurations where log file is stored in a directory writable to the mysql OS user. If log file is stored in the /var/log directory, mysql user is not able to replace it with a link to some other file.
This issue was fixed in MySQL versions 5.5.54, 5.6.35, and 5.7.17. The following related entry can be found in the release notes:
Initialization scripts create the error log file only if the base directory is /var/log or /var/lib.

The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image.
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.
It was reported [1] that the gdImageCreateFromXpm() function in libgd could dereference a NULL pointer, noting:
"The call to strlen() parses image.colorTable[i].ccolor which is initialised as NULL if the particular color mapping uses a different key (such as monochrome/monovisual)."
This was reported against PHP, which includes an embedded copy of the gd library. CVE-2014-2497 was assigned to this issue [2].
