Fasterxml Jackson version Before 2.9.8 contains a CWE-20: Improper Input Validation vulnerability in Jackson-Modules-Java8 that can result in Causes a denial-of-service (DoS). This attack appear to be exploitable via The victim deserializes malicious input, specifically very large values in the nanoseconds field of a time value. This vulnerability appears to have been fixed in 2.9.8.
A vulnerability was found in OpenSSL 1.0.2. When an application encounters a fatal protocol error and then calls SSLshutdown() twice, OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. This difference in behaviour can be detected by a remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Also the application must call SSLshutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). AEAD ciphersuites are not impacted. This issue does not impact OpenSSL 1.1.1 or 1.1.0.

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 flaw was found in the Linux kernel implementation of userspace core dumps. This flaw allows anyone with access to core dumps to see a small amount of private kernel data about the current running kernels internal state which could be used to further allow an attack to more reliably execute. This information could be user processes or kernel state from previous executions.

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in mutexlock in kernel/locking/mutex.c. This is related to mutexcanspinonowner in kernel/locking/mutex.c, btrfsqgroupfreemeta in fs/btrfs/qgroup.c, and btrfsinsertdelayeditems in fs/btrfs/delayed-inode.c.

In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsemdownwriteslowpath use-after-free because (in rwsemcanspinonowner in kernel/locking/rwsem.c) rwsemownerflags returns an already freed pointer,
In SQLite through 3.29.0 whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlitestat1 sz field aka a "severe division by zero in the query planner."
drivers/net/wireless/ath/ath6kl/usb.c in the Linux kernel through 5.2.9 has a NULL pointer dereference via an incomplete address in an endpoint descriptor.

OpenSSH is vulnerable to a man-in-the-middle attack, caused by an observable discrepancy flaw. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.

Integer overflows were discovered in the functions grubcmdinitrd and grubinitrdinit in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
A flaw was found in the way the Jar URL handler in the Networking component in OpenJDK handled URLs with nested jar: URLs. A specially crafted URL could cause Java application to exit when parsed.
An out of bounds access flaw was found in the optimized implementation of String indexof() method for x86 platform in the Hotspot component of OpenJDK. This could cause Java Virtual Machine to crash or disclose limited information about the memory content.
