Apache Accumulo versions 1.5.0 through 1.10.0 and version 2.0.0 do not properly check the return value of some policy enforcement functions before permitting an authenticated user to perform certain administrative operations. Specifically, the return values of the 'canFlush' and 'canPerformSystemActions' security functions are not checked in some instances, therefore allowing an authenticated user with insufficient permissions to perform the following actions: flushing a table, shutting down Accumulo or an individual tablet server, and setting or removing system-wide Accumulo configuration properties.

Dell BSAFE Micro Edition Suite, versions prior to 4.5, are vulnerable to an Unchecked Return Value Vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability to modify and corrupt the encrypted data.

A denial of service issue was addressed with improved state handling. This issue is fixed in macOS Big Sur 11.0.1. An attacker may be able to bypass Managed Frame Protection.

manual/search.texi in the GNU C Library (aka glibc) before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999.

In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes an invalid argument to `dlpack.to_dlpack` the expected validations will cause variables to bind to `nullptr` while setting a `status` variable to the error condition. However, this `status` argument is not properly checked. Hence, code following these methods will bind references to null pointers. This is undefined behavior and reported as an error if compiling with `-fsanitize=null`. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

IBM Business Automation Workflow 18.0, 19.0, and 20.0 and IBM Business Process Manager 8.0, 8.5, and 8.6 could allow a remote attacker to obtain sensitive information when a detailed technical error message is returned in the browser. This information could be used in further attacks against the system. IBM X-Force ID: 182715.

A code execution vulnerability exists in the DICOM parse_dicom_meta_info functionality of Accusoft ImageGear 19.7. A specially crafted malformed file can cause an out-of-bounds write. An attacker can trigger this vulnerability by providing a victim with a malicious DICOM file.

An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability.

The URL parser in Microsoft Internet Information Services (IIS) 5.1 on Windows XP Professional SP2 allows remote attackers to execute arbitrary code via multiple requests to ".dll" followed by arguments such as "~0" through "~9", which causes ntdll.dll to produce a return value that is not correctly handled by IIS, as demonstrated using "/_vti_bin/.dll/*/~0". NOTE: the consequence was originally believed to be only a denial of service (application crash and reboot).

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service (resource exhaustion) by causing file descriptors to be assigned and not released, as demonstrated by fanta.
