Ubuntu Security Notice 6430-1 - It was discovered that FFmpeg did not properly handle certain inputs in vf_lagfun.c, resulting in a buffer overflow vulnerability. An attacker could possibly use this issue to cause a denial of service via application crash. This issue only affected Ubuntu 20.04 LTS. It was discovered that FFmpeg incorrectly managed memory in avienc.c, resulting in a memory leak. An attacker could possibly use this issue to cause a denial of service via application crash.

The Embed Calendly plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'calendly' shortcode in versions up to, and including, 3.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

An Improperly Implemented Security Check for Standard vulnerability in storm control of Juniper Networks Junos OS QFX5k devices allows packets to be punted to ARP queue causing a l2 loop resulting in a DDOS violations and DDOS syslog. This issue is triggered when Storm control is enabled and ICMPv6 packets are present on device. This issue affects Juniper Networks: Junos OS * All versions prior to 20.2R3-S6 on QFX5k; * 20.3 versions prior to 20.3R3-S5 on QFX5k; * 20.4 versions prior to 20.4R3-S5 on QFX5k; * 21.1 versions prior to 21.1R3-S4 on QFX5k; * 21.2 versions prior to 21.2R3-S3 on QFX5k; * 21.3 versions prior to 21.3R3-S2 on QFX5k; * 21.4 versions prior to 21.4R3 on QFX5k; * 22.1 versions prior to 22.1R3 on QFX5k; * 22.2 versions prior to 22.2R2 on QFX5k.

A memory leak in tsMuxer version git-2539d07 allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file.

BeyondTrust Privileged Remote Access (PRA) versions 22.2.x to 22.4.x are vulnerable to a local authentication bypass. Attackers can exploit a flawed secret verification process in the BYOT shell jump sessions, allowing unauthorized access to jump items by guessing only the first character of the secret.

Plus, many of the world’s largest cloud providers are warning of a vulnerability that attackers exploited in August to launch the largest distributed denial-of-service attack on record.

The threat actors behind ShellBot are leveraging IP addresses transformed into its hexadecimal notation to infiltrate poorly managed Linux SSH servers and deploy the DDoS malware. "The overall flow remains the same, but the download URL used by the threat actor to install ShellBot has changed from a regular IP address to a hexadecimal value," the AhnLab Security Emergency response Center (ASEC)

The Etsy Shop plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'etsy-shop' shortcode in versions up to, and including, 3.0.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
