LAYER: meta PACKAGE NAME: libtirpc PACKAGE VERSION: 1.3.4 CVE: CVE-2013-1950 CVE STATUS: Patched CVE SUMMARY: The svc_dg_getargs function in libtirpc 0.2.3 and earlier allows remote attackers to cause a denial of service (rpcbind crash) via a Sun RPC request with crafted arguments that trigger a free of an invalid pointer. CVSS v2 BASE SCORE: 4.3 CVSS v3 BASE SCORE: 0.0 VECTOR: NETWORK VECTORSTRING: AV:N/AC:M/Au:N/C:N/I:N/A:P MORE INFORMATION: https://nvd.nist.gov/vuln/detail/CVE-2013-1950 LAYER: meta PACKAGE NAME: libtirpc PACKAGE VERSION: 1.3.4 CVE: CVE-2017-8779 CVE STATUS: Patched CVE SUMMARY: 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. CVSS v2 BASE SCORE: 7.8 CVSS v3 BASE SCORE: 7.5 VECTOR: NETWORK VECTORSTRING: AV:N/AC:L/Au:N/C:N/I:N/A:C MORE INFORMATION: https://nvd.nist.gov/vuln/detail/CVE-2017-8779 LAYER: meta PACKAGE NAME: libtirpc PACKAGE VERSION: 1.3.4 CVE: CVE-2018-14621 CVE STATUS: Patched CVE SUMMARY: An infinite loop vulnerability was found in libtirpc before version 1.0.2-rc2. With the port to using poll rather than select, exhaustion of file descriptors would cause the server to enter an infinite loop, consuming a large amount of CPU time and denying service to other clients until restarted.

The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections. CVSS v2 BASE SCORE: 5.0 CVSS v3 BASE SCORE: 5.3 VECTOR: NETWORK VECTORSTRING: AV:N/AC:L/Au:N/C:N/I:N/A:P MORE INFORMATION: https://nvd.nist.gov/vuln/detail/CVE-2018-14622 LAYER: meta PACKAGE NAME: libtirpc PACKAGE VERSION: 1.3.4 CVE: CVE-2021-46828 CVE STATUS: Patched CVE DETAIL: fixed-version CVE DESCRIPTION: fixed in 1.3.3rc1 so not present in 1.3.3 CVE SUMMARY: In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections.
