ILASM is vulnerable to a buffer overflow. By creating a malicious .il file containing a call to a function greater than 64K, an attacker could overflow a buffer and execute arbitrary code on the system, if the attacker could persuade a victim to assemble the malicious .il file using ILASM.
Platforms Affected:
- Microsoft, .NET Framework 1.0
- Microsoft, .NET Framework 1.1 sp1
- Microsoft, .NET Framework 1.1
