Yderligere oplysninger:

Der rapporteres om en race-tilstand i libnss-ldap, et NSS-modul til anvendelse af LDAP som naming-tjenste, hvilket kunne forårsage lammelsesangreb (denial of service) hvis applikationer anvender pthreads.

Problemet blev fundet i IMAP/POP-serveren dovecot, men påvirker potentielt flere programmer.

I den gamle stabile distribution (sarge), er dette problem rettet i version 238-1sarge1.

I den stabile distribution (etch), er dette problem rettet i version 251-7.5etch1.

I den ustabile distribution (sid), er dette problem rettet i version 256-1.

Vi anbefaler at du opgraderer din libnss-ldap-pakke.
