libotr is a portable off-the-record messaging library.

Multiple heap-based buffer overflows are present in the Base64 decoder of libotr.

A remote attacker could send a specially crafted OTR message, resulting in arbitrary code execution with the privileges of the process or a Denial of Service condition.

There is no known workaround at this time.

All libotr users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/libotr-3.2.1" CVE-2012-3461 creffett creffett
