Amazon Linux 1 Security Advisory: ALAS-2014-397
Advisory Release Date: 2014-09-03 14:37 Pacific
Advisory Updated Date: 2014-09-19 11:49 Pacific
The (1) serf_ssl_cert_issuer, (2) serf_ssl_cert_subject, and (3) serf_ssl_cert_certificate functions in Serf 0.2.0 through 1.3.x before 1.3.7 does not properly handle a NUL byte in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
Affected Packages:
libserf
Issue Correction:
Run yum update libserf to update your system.
