Mutt IMAP namespace buffer overflow
| mutt-imap-namespace-bo (27428) |  High Risk |
Description:
Mutt is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the browse_get_namespace() function in browse.c. If a remote attacker could convince the victim to connect to a malicious IMAP server, then the attacker could send an overly long namespace from the IMAP server to overflow a buffer and execute arbitrary code on the system or cause the application to crash.
