Allele Security Alert
Out-of-bounds reads with specially crafted SFTP packets
The libssh2 project
libssh2 versions 0.3 up to and including 1.8.0
Proof of concept
A server could send a specially crafted partial SFTP packet with a empty payload in response to various SFTP commands such as read directory, file status, status vfs and symlink. The result would be a memory out of bounds read (CWE-130).
