This vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read.

The Cisco PSIRT is aware that proof-of-concept exploit code is available for the vulnerabilities that are described in this advisory.
The Cisco PSIRT is not aware of any malicious use of the vulnerabilities that are described in this advisory.

Two more Cisco security advisories:

• Cisco Meeting Management REST API Privilege Escalation Vulnerability CVE-2025-20156 (9.9 critical)
• Cisco BroadWorks SIP Denial of Service Vulnerability CVE-2025-20165 (7.5 high)

I just went through @drawio 's homepage so I can throw some money at them, but I just can't because disrupting unhealthy markets is its own reward it seems:

These people are pretty cool!

It's flattering when your work appears in the news, I just wish this piece wasn't so terribly wrong on so many important details :P

I'll reshare the original instead: https://blog.silentsignal.eu/2025/01/21/ibm-acs-password-dump/

Oracle: Oracle Critical Patch Update Advisory - January 2025
It's a pain in the butt to read, but there's 300+ vulnerabilities and coupled with the Oracle VP of Security Assurance's blog post January 2025 Critical Patch Update Released, there's likely no mention of exploitation.

Well that's awkward. @EQSTLab used a OS command injection bug, but it was one used last year. Alpine chose not to patch it since "in accordance with ISO21434...the vulnerability is classified as 'Sharing the Risk'." Yikes. The @EQSTLab team earns $5,000 and 1 Master of Pwn point.

There's a "Signal deanonymized" thing going around:

Stay calm. Deep breaths.

👉 while this is a real consideration, the only thing the attacker gets from this is a very rough (kilometers or tens of kilometers radius) location

👉 other communication platforms that use any kind of caching CDN to deliver attachments are just as vulnerable

👉 you almost certainly should continue to use Signal, unless you specifically know that this is a big problem for you.
