CVE-2009-20007 | Talkative IRC v0.4.4.16 is vulnerable to a stack-based buffer overflow when processing specially crafted response strings sent to a connected client. An attacker can exploit this flaw by sending an overly long message that overflows a fixed-length buffer, potentially leading to arbitrary code execution in the context of the vulnerable process. This vulnerability is exploitable remotely and does not require authentication.

Klassifikation & Betroffenheit:

Talkative Talkative IRC 0 ≤0.4.4.16

Improper Restriction of Operations within the Bounds of a Memory Buffer 🎯 High

The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

🛡️ Empfohlene Mitigation: Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow prot…
