MiracleLinux 7 : libtirpc-0.2.4-0.8.0.1.el7.AXS7 (AXSA:2017-1681:01)

high Nessus Plugin ID 290132

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2017-1681:01 advisory.

 This package contains SunLib's implementation of transport-independent RPC (TI-RPC) documentation. This library forms a piece of the base of Open Network Computing (ONC), and is derived directly from the Solaris 2.3 source.
 TI-RPC is an enhanced version of TS-RPC that requires the UNIX System V Transport Layer Interface (TLI) or an equivalent X/Open Transport Interface (XTI). TI-RPC is on-the-wire compatible with the TS-RPC, which is supported by almost 70 vendors on all major operating systems. TS-RPC source code (RPCSRC 4.0) remains available from several internet sites.
 Security issues fixed with this release:
 CVE-2017-8779 rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc through 1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC data size during memory allocation for XDR strings, which allows remote attackers to cause a denial of service (memory consumption with no subsequent free) via a crafted UDP packet to port 111, aka rpcbomb.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libtirpc package.
