An issue was discovered in Xen through 4.14.x. Neither xenstore implementation does any permission checks when reporting a xenstore watch event. A guest administrator can watch the root xenstored node, which will cause notifications for every created, modified, and deleted key. A guest administrator can also use the special watches, which will cause a notification every time a domain is created and destroyed. Data may include: number, type, and domids of other VMs; existence and domids of driver domains; numbers of virtual interfaces, block devices, vcpus; existence of virtual framebuffers and their backend style (e.g., existence of VNC service); Xen VM UUIDs for other domains; timing information about domain creation and device setup; and some hints at the backend provisioning of VMs and their devices. The watch events do not contain values stored in xenstore, only key names. A guest administrator can observe non-sensitive domain and device lifecycle events relating to other guests. This information allows some insight into overall system configuration (including the number and general nature of other guests), and configuration of other guests (including the number and general nature of other guests' devices). This information might be commercially interesting or might make other attacks easier. There is not believed to be exposure of sensitive data. Specifically, there is no exposure of VNC passwords, port numbers, pathnames in host and guest filesystems, cryptographic keys, or within-guest data.
kinit in KDE Frameworks before 5.23.0 uses weak permissions (644) for /tmp/xauth-xxx-_y, which allows local users to obtain X11 cookies of other users and consequently capture keystrokes and possibly gain privileges by reading the file.
The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.
log4js-node is a port of log4js to node.js. In affected versions default file permissions for log files created by the file, fileSync and dateFile appenders are world-readable (in unix). This could cause problems if log files contain sensitive information. This would affect any users that have not supplied their own permissions for the files via the mode parameter in the config. Users are advised to update.
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.
LXD before 2.0.2 uses world-readable permissions for /var/lib/lxd/zfs.img when setting up a loop based ZFS pool, which allows local users to copy and read data from arbitrary containers via unspecified vectors.
NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer handler, where an unprivileged regular user can cause an integer to be truncated, which may lead to denial of service or data tampering.
LXD before 2.0.2 does not properly set permissions when switching an unprivileged container into privileged mode, which allows local users to access arbitrary world readable paths in the container directory via unspecified vectors.
The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize a certain block of heap memory, which allows local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value, a different vulnerability than CVE-2010-2478.
The compat_get_timex function in kernel/compat.c in the Linux kernel before 4.16.9 allows local users to obtain sensitive information from kernel memory via adjtimex.
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

NVIDIA GPU software for Linux contains a vulnerability where it can expose sensitive information to an actor that is not explicitly authorized to have access to that information. A successful exploit of this vulnerability might lead to information disclosure.
The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image.
The processutils.execute function in OpenStack oslo-incubator, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 allows local users to obtain passwords from commands that cause a ProcessExecutionError by reading the log.
Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576.
A flaw was found in Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when using modules which decrypts vault files such as assemble, script, unarchive, win_copy, aws_s3 or copy modules. The temporary directory is created in /tmp leaves the s ts unencrypted. On Operating Systems which /tmp is not a tmpfs but part of the root partition, the directory is only cleared on boot and the decryp emains when the host is switched off. The system will be vulnerable when the system is not running. So decrypted data must be cleared as soon as possible and the data which normally is encrypted ble.
A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.
