CVE-2026-63090 ProFTPD mod_sftp Heap Buffer Overflow via SFTP Packet Reassembly

ProFTPD before 1.3.9c and 1.3.10rc3 contains a heap-based buffer overflow vulnerability in the modsftp module that allows authenticated low-privilege attackers to achieve arbitrary code execution by sending crafted SFTP packet fragments exceeding the 16 KB reassembly buffer in the fxp.c component...

CVE-2026-63090

ProFTPD mod_sftp in fxp.c suffers a heap-based buffer overflow when oversized SFTP packet fragments exceed the 16 KB reassembly buffer. In ProFTPD 1.3.9c and 1.3.10rc3, authenticated low-priv attackers can cause arbitrary code execution by manipulating reallocation and memory, including overwriti...
