A project that aims at giving high performance, scalable, and fault tolerant access to data repositories of many kinds.
A shell command injection was discovered in XRootD.
A remote attacker could execute arbitrary code.
There is no known workaround at this time.
All XRootD users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/xrootd-4.8.3"
