> CVE-2011-2729: Commons Daemon fails to drop capabilities
> Severity: high
> Vendor:
> The Apache Software Foundation
> Versions Affected:
> Commons Daemon 1.0.3 to 1.0.6
> Additionally, these vulnerabilities only occur when all of the
> following are true:
> a) running on Linux operating system
> b) jsvc was compiled with libcap
> c) -user parameter is used
> Description:
> Due to bug in capabilities code, jsvc does not drop capabilities
> allowing the application to access files and directories owned by
> superuser.
> Mitigation:
> Affected users of all versions can mitigate these vulnerabilities by
> taking any of the following actions:
> a) upgrade to a version where the vulnerabilities have been fixed
> jsvc 1.0.3 - 1.0.6 users should upgrade to 1.0.7 version
> b) do not use -user parameter to switch user
> c) recompile the jsvc without libcap support
> Example:
> [root@fedora jsvctest]# ./jsvc -cp commons-daemon-1.0.6.jar:. -user jsvc ....
> [root@fedora jsvctest]# grep ^Cap /proc/<pid>/status
> CapInh: 0000000000000406
> CapPrm: 0000000000000406
> CapEff: 0000000000000406
> CapBnd: ffffffffffffffff
> [root@fedora jsvctest]# ./jsvc -cp commons-daemon-1.0.7.jar:. -user jsvc ....
> [root@fedora jsvctest]# grep ^Cap /proc/<pid>/status
> CapInh: 0000000000000000
> CapPrm: 0000000000000000
> CapEff: 0000000000000000
> CapBnd: ffffffffffffffff
