Rule: -- Sid: 1936 -- Summary: This event is generated when an attempt is made to exploit a buffer overflow condition in the Post Office Protocol (POP) command FOLD. -- Impact: Possible remote execution of arbitrary code leading to a remote root compromise. -- Detailed Information: A vulnerability exists such that an attacker may overflow a buffer by sending data where a line feed character should occur to a POP server via the FOLD command. The FOLD command allows the user to specify a mail folder to select. By specifying a very large argument, the user can exploit the buffer overflow condition. -- Affected Systems POP Servers -- Attack Scenarios: Simple. An attacker can supply specially crafted packets to a POP server via the FOLD function. -- Ease of Attack: Simple. -- False Positives: None Known -- False Negatives: None Known -- Corrective Action: Upgrade to the latest non-affected version of the software. -- Contributors: Sourcefire Research Team Brian Caswell <bmc@sourcefire.com> Nigel Houghton <nigel.houghton@sourcefire.com> Ricky Macatee <ricky.macatee@sourcefire.com> -- Additional References: --
