Yahoo has released an update to its IM software that patches a security hole found last week. Yahoo has issued an update to its instant-messaging software, in order to address a security flaw found in the application. The company said the security issue was related to a buffer overflow, which is a common security vulnerability in computer programs written in C and C++ that allows more information to be added to a chunk of memory than it was designed to hold. Typical problems involved in an instant-messaging-related buffer overflow might include an involuntarily log-out of an IM session, a crash of browsing software applications, and a possible introduction of executable code. The last of the potential problems would likely cause the most damage, as the code might allow a malicious programmer to take control of a user’s machine, delete files and otherwise wreak havoc with a victim’s computer system.
