9.0 HIGH — AV:N/AC:L/Au:S/C:C/I:C/A:C

Description

The auth_gssapi_unwrap_data function in lib/rpc/auth_gssapi_misc.c in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 does not properly handle partial XDR deserialization, which allows remote authenticated users to cause a denial of service (use-after-free and double free, and daemon crash) or possibly execute arbitrary code via malformed XDR data, as demonstrated by data sent to kadmind.

Affected configurations

• mit kerberos 5 1.11 • mit kerberos 5 1.11.1 • mit kerberos 5 1.11.2 • mit kerberos 5 1.11.3 • mit kerberos 5 1.11.4 • mit kerberos 5 1.11.5 • mit kerberos 5 1.12 • mit kerberos 5 1.12.1 • mit kerberos 5 1.12.2 • mit kerberos 5 1.13
