Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port 111, a related issue to CVE-2017-8779.
