BootPerformanceTable pointer is read from an NVRAM variable in PEI. Recommend setting PcdFirmwarePerformanceDataTableS3Support to FALSE.

A heap overflow in LzmaUefiDecompressGetInfo function in EDK II.

An unlimited recursion in DxeCore in EDK II.

An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink it incorrectly also creates the target of the symlink as an empty file which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists then the contents of that file correctly remain unchanged.)

ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios such as unconstrained agent-socket access on a legacy operating system or the forwarding of an agent to an attacker-controlled host.

A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37 10.3 before 10.3.28 10.4 before 10.4.18 and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product.

The ClamAV Engine (version 0.103.1 and below) component embedded in Storsmshield Network Security (SNS) is subject to DoS in case of parsing of malformed png files. This affect Netasq versions 9.1.0 to 9.1.11 and SNS versions 1.0.0 to 4.2.0. This issue is fixed in SNS 3.7.19 3.11.7 and 4.2.1.

An issue was discovered in the rand_core crate before 0.6.2 for Rust. Because read_u32_into and read_u64_into mishandle certain buffer-length checks a random number generator may be seeded with too little data.

Controller/Backend/FileEditController.php and Controller/Backend/FilemanagerController.php in Bolt before 4.1.13 allow Directory Traversal.

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI and has a length up to the maximum length of a Netlink message.

An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages.

An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem the transport's handle is available to unprivileged users via the sysfs file system at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables.

An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to memory corruption.

An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform the length would be truncated modulo 2**32 causing unintended length truncation.

In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime.
