Scientific Linux Security Update : krb5 on SL6.x i386/x86_64
Medium Nessus Plugin ID 90145
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA memory leak flaw was found in the krb5_unparse_name() function of the MIT Kerberos kadmind service. An authenticated attacker could repeatedly send specially crafted requests to the server, which could cause the server to consume large amounts of memory resources, ultimately leading to a denial of service due to memory exhaustion.
An out-of-bounds read flaw was found in the kadmind service of MIT Kerberos. An authenticated attacker could send a maliciously crafted message to force kadmind to read beyond the end of allocated memory, and write the memory contents to the KDC database if the attacker has write permission, leading to information disclosure. (CVE-2015-8629)
After installing the updated packages, running Kerberos services (krb5kdc, kadmin, and kprop) will be restarted automatically.
SolutionUpdate the affected packages.
