From version 1.3.0 onward, Apache Spark's standalone master exposes a REST API for job submission, in addition to the submission mechanism used by spark-submit. In standalone, the config property 'spark.authenticate.secret' establishes a shared secret for authenticating requests to submit jobs via spark-submit. However, the REST API does not use this or any other authentication mechanism, and this is not adequately documented. In this case, a user would be able to run a driver program without authenticating, but not launch executors, using the REST API. This REST API is also used by Mesos, when set up to run in cluster mode (i.e., when also running MesosClusterDispatcher), for job submission. Future versions of Spark will improve documentation on these points, and prohibit setting 'spark.authenticate.secret' when running the REST APIs, to make this clear. Future versions will also disable the REST API by default in the standalone master by changing the default value of 'spark.master.re...

MP4NameFirstMatches in mp4util.cpp in MP4v2 2.0.0 mishandles substrings of atom names, leading to use of an inappropriate data type for associated atoms. The resulting type confusion can cause out-of-bounds memory access.

MP4Atom::factory in mp4atom.cpp in MP4v2 2.0.0 incorrectly uses the MP4ItemAtom data type in a certain case where MP4DataAtom is required, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted MP4 file, because access to the data structure has different expectations about layout as a result of this type confusion.

A double free exists in the MP4StringProperty class in mp4property.cpp in MP4v2 2.0.0. A dangling pointer is freed again in the destructor once an exception is triggered.

IBM Power HMC 7.1.0 through 7.8.0 and 7.3.5 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.  IBM X-Force ID:  91163.

ncmpc through 0.29 is prone to a NULL pointer dereference flaw. If a user uses the chat screen and another client sends a long chat message, a crash and denial of service could occur.

IBM Tivoli Workload Automation for AIX (IBM Workload Scheduler 8.6, 9.1, 9.2, 9.3, and 9.4) contains directories with improper permissions that could allow a local user to with special access to gain root privileges. IBM X-Force ID: 138208.

The __oom_reap_task_mm function in mm/oom_kill.c in the Linux kernel before 4.14.4 mishandles gather operations, which allows attackers to cause a denial of service (TLB entry leak or use-after-free) or possibly have unspecified other impact by triggering a copy_to_user call within a certain time window.

drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.

crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls.
