Details

It was discovered that curl incorrectly handled SASL authentication when
communicating over POP3, SMTP or IMAP. If a user or automated system were
tricked into processing a specially crafted URL, an attacker could cause
a denial of service, or possibly execute arbitrary code. The default
compiler options for affected releases should reduce the vulnerability to a
denial of service.
