Descriptions

Use-after-free vulnerability in xprt_set_caller in rpcb_svc_com.c in rpcbind 0.2.1 and earlier allows remote attackers to cause a denial of service (daemon crash) via crafted packets, involving a PMAP_CALLIT code.

Vulnerabilidad de uso después de liberación de memoria en xprt_set_caller en rpcb_svc_com.c en rpcbind 0.2.1 y versiones anteriores, permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de paquetes manipulados, implicando un código PMAP_CALLIT.

A use-after-free flaw related to the PMAP_CALLIT operation and TCP/UDP connections was discovered in rpcbind. A remote, unauthenticated attacker could possibly exploit this flaw to crash the rpcbind service (denial of service) by performing a series of UDP and TCP calls.
