CVE-2010-4341 sssd: DoS in sssd PAM responder can prevent logins
Sebastian Krahmer discovered that it was possible to make sssd hang forever inside a loop in the pam_parse_in_data_v2() function of SSSD's PAM responder by using a carefully crafted packet to sssd. This could be exploited by a local attacker to crash sssd and prevent other legitimate users from logging into the system.

Red Hat would like to thank Sebastian Krahmer for reporting this issue.
