ClamAV DoS Vulnerability: Cisco’s Patch Saves the Day, But Exploit Looms!
Cisco patches a ClamAV DoS vulnerability with proof-of-concept exploit code available. Tracked as CVE-2025-20128, it involves a heap-based buffer overflow in OLE2 decryption. Although there’s no evidence of active exploitation, the exploit code is out there, eagerly waiting like a cat outside a tuna factory.
Hot Take:
When it comes to cybersecurity, Cisco seems to be playing whack-a-mole with vulnerabilities. This time, they’ve patched a bug that can crash ClamAV faster than a toddler who just discovered the power button on your computer. Kudos to Cisco for getting ahead of the game, but maybe they should consider hiring a few more digital exterminators.
Key Points:
- Cisco patches a ClamAV DoS vulnerability (CVE-2025-20128) caused by a heap-based buffer overflow.
- The flaw allows unauthenticated, remote attackers to crash the ClamAV antivirus scanning process.
- Proof-of-concept exploit code is already available, but no active exploitation has been detected.
- Other recent patches include DoS and privilege escalation vulnerabilities in various Cisco products.
- Cisco claims overall system stability won’t be affected despite successful ClamAV DoS attacks.
