Ross Boylan discovered a remote buffer overflow in fetchmail. By sending invalid responses with very long UIDs, a faulty or malicious POP server could crash fetchmail or execute arbitrary code with the privileges of the user invoking fetchmail.
fetchmail is commonly run as root to fetch mail for multiple user accounts; in this case, this vulnerability could be exploited to compromise the whole system.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
