Security flaws in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD)Security flaws in Cisco

We have three new vulnerabilities in Cisco.

One could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition.
One that could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system with root-level privileges. Administrator-level privileges are required to exploit this vulnerability.
And another one which could allow an authenticated, local attacker to execute arbitrary code with root-level privileges. Administrator-level privileges are required to exploit this vulnerability.

Vulnerabilities in Adobe Premiere Pro and Adobe Bridge founded

ZDI-24-292: Adobe Premiere Pro AVI File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adobe Premiere Pro. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The ZDI has assigned a CVSS rating of 7.8. The following CVEs are assigned: CVE-2024-20745.
http://www.zerodayinitiative.com/advisories/ZDI-24-292/

The specific flaw exists within the parsing of AVI files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Adobe has issued an update to correct this vulnerability. More details can be found at:
