Summary
libnfs security update
Details

Package contains a library of functions for accessing NFSv2 and NFSv3 servers from user space. It provides a low-level,asynchronous RPC library for accessing NFS protocols, an asynchronous library with POSIX-like VFS functions,and a synchronous library with POSIX-like VFS functions.

Security Fix(es):

libnfs through 6.0.2 before 55c18ea does not validate a string size, leading to an integer overflow during a connection to a crafted NFS server. This occurs in libnfszdrstring in lib/libnfs-zdr.c.(CVE-2026-53689)
