Title
Обновление USN-1062-1 -- уязвимости krb5
Description
Keiichi Mori discovered that the MIT krb5 KDC database propagation daemon is vulnerable to a denial of service attack due to improper logic when a worker child process exited because of invalid network input. This could only occur when kpropd is running in standalone mode; kpropd was not affected when running in incremental propagation mode or as an inetd server. This issue only affects Ubuntu 9.10, Ubuntu 10.04 LTS, and Ubuntu 10.10. Kevin Longfellow and others discovered that the MIT krb5 Key Distribution Center daemon is vulnerable to denial of service attacks when using an LDAP back end due to improper handling of network input

Comment
: The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (NULL pointer dereference or buffer over-read, and daemon crash) via a crafted principal name.

Comment
: The unparse implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (file descriptor exhaustion and daemon hang) via a principal name that triggers use of a backslash escape sequence, as demonstrated by a \n sequence.

Comment
: The do_standalone function in the MIT krb5 KDC database propagation daemon (kpropd) in Kerberos 1.7, 1.8, and 1.9, when running in standalone mode, does not properly handle when a worker child process "exits abnormally," which allows remote attackers to cause a denial of service (listening process termination, no new connections, and lack of updates in slave KVC) via unspecified vectors.
