CVE-2017-8804

CVE-2017-8804 describes a denial-of-service vulnerability in the GNU C Library (glibc) version 2.25. Specifically, the xdr_bytes and xdr_string functions mishandle buffer deserialization failures. This allows remote attackers to cause a denial of service through excessive virtual memory allocation or memory consumption by sending a crafted UDP packet to port 111. The vulnerability has a CVSS v3 score of 7.5 (High), indicating a network-based attack with low complexity and high impact on availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
