RHBA-2010:0013 - selinux-policy bug fix update

Synopsis

selinux-policy bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated selinux-policy packages that fix several bugs are now available.

Description

The selinux-policy packages contain the rules that govern how confined processes run on the system.

These updated selinux-policy packages provide fixes for the following bugs:

  • the "setkey" utility from the ipsec-tools package manipulates and dumps the kernel's Security Policy Database (SPD) entries and Security Association Database (SAD) entries. The current selinux-policy did not allow users running under the "sysadm" role to use setkey. This update allows users running under the sysadm SELinux role to use the setkey utility from the ipsec-tools package. (BZ#538449)

  • using the Openswan implementation of IPsec could have resulted in AVC (Access Vector Cache) denials causing the integrity check to fail, which in turn would cause the pluto key management daemon not to start. This update includes updated policy rules for IPsec which fix the AVC denials so that pluto is allowed to run as expected. Note that this is necessary for FIPS-140 compliance. (BZ#538452)

  • SELinux denials caused by the ssh-keygen's "system_u:object_r:initrc_exec_t" context caused ssh-keygen to fail to generate public/private RSA key pairs. These updated SELinux policy rules allow ssh-keygen to successfully generate public/private RSA key pairs as expected. (BZ#538453)

  • when the "ifup" script was run manually in order to activate the first IPsec interface, which then attempts to start racoon, racoon incorrectly ran under the "unconfined_t" context instead of under the expected "racoon_t", thus preventing it from starting. Note that this did not happen when the IPsec network interface configuration file contained an "ONBOOT=yes" parameter; racoon successfully started in this case. With this update, racoon possesses the correct context, "racoon_t", which allows it to run when started via the ifup network startup script. (BZ#538503)

All users are advised to upgrade to these updated packages, which resolve these issues.
