Description Martin Prpič 2014-01-24 10:13:33 UTC

It was found [1] that the installcheck-local.sh script of the syncevolution package creates temporary files in an insecure way. A local attacker could use these flaws to perform a symbolic link attack on the temporary files used by installcheck-local.sh.

NOTE: The vulnerable installcheck-local.sh script is not shipped in the syncevolution RPM package, but is included in the source and may be called at compile time. This flaw is therefore only a concern for those rebuilding the SRPM package. Regular users of the syncevolution package are not affected.
