Title: libesmtp read_smtp_response Buffer Overflow Vulnerability
Severity: HIGH
Description:
libesmtp is a library used by the Balsa e-mail client. Balsa is a graphical e-mail client that incorporates some of the codebase from the mutt e-mail client.
A buffer overflow vulnerability has been reported in libesmtp that may allow an attacker to execute code.
The vulnerability occurs in the read_smtp_response() function in the protocol.c source file.
An attacker can exploit this vulnerability by enticing a victim user to connect to an attacker-controlled SMTP (Simple Mail Transfer Protocol) server and sending a specially crafted response.
Successful exploitation of this vulnerability will result in the execution of attacker-supplied code.
This vulnerability was reported for the libesmtp library prior to 0.8.11.
