This update fixes several one-byte buffer overruns in the imap annote extension as well as in cached header handling which can be run by an authenticated user. Additionally bounds checking in fetchnews was improved to avoid exploitation by a peer news admin. Please note that one-byte buffer overflows can not be exploited to execute arbitrary commands by manipulating the saved registers on the stack if the compiler used (gcc >= 3) aligns the stack space. Nevertheless the code behaviour may be manipulated by overwriting local variables. The result is not known but ranges between a denial-of-service condition and privilege escalation.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
