CVE-2014-5352

Incorrect memory management in the libgssapi_krb5 library might result in denial of service or the execution of arbitrary code.

CVE-2014-9421

Incorrect memory management in kadmind's processing of XDR data might result in denial of service or the execution of arbitrary code.

CVE-2014-9422

Incorrect processing of two-component server principals might result in impersonation attacks.

CVE-2014-9423

An information leak in the libgssrpc library.

For the stable distribution (wheezy), these problems have been fixed in version 1.10.1+dfsg-5+deb7u3.

For the unstable distribution (sid), these problems have been fixed in version 1.12.1+dfsg-17.

We recommend that you upgrade your krb5 packages.");
