[GLSA-200605-05] rsync: Potential integer overflow Vulnerability Scan
Vulnerability Scan Summary
rsync: Potential integer overflow
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200605-05
(rsync: Potential integer overflow)
An integer overflow was found in the receive_xattr function from
the extended attributes patch (xattr.c) for rsync. The vulnerable
function is only present when the "acl" USE flag is set.
Impact
A remote attacker with write access to an rsync module could craft
malicious extended attributes which would trigger the integer overflow,
potentially resulting in the execution of arbitrary code with the
rights of the rsync daemon.
Workaround
Do not provide write access to an rsync module to untrusted
parties.

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/rsync-2.6.8"
Threat Level: High
