**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** This vulnerability's attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require man-in-the-middle type setups or that rely on initially gaining a foothold in another environment.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

A potential security vulnerability has been identified in Integrated Lights-Out 4 (iLO 4). The vulnerability could allow remote Denial of Service. The vulnerability is resolved in Integrated Lights-Out 4 (iLO 4) 2.80 and later.

There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.

Ubuntu Security Notice 5244-2 - USN-5244-1 fixed a vulnerability in DBus. This update provides the corresponding update for Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Daniel Onaca discovered that DBus contained a use-after-free vulnerability, caused by the incorrect handling of usernames sharing the same UID. An attacker could possibly use this issue to cause DBus to crash, resulting in a denial of service.

NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 in GitHub repository vim/vim prior to 8.2.4901. NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 allows attackers to cause a denial of service (application crash) via a crafted input.

All versions of the npm package bignum are vulnerable to Denial of Service (DoS) due to a type-check exception in V8. When verifying the type of the second argument to the .powm function, V8 will crash regardless of Node try/catch blocks.
