rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote     attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use     beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.
    (CVE-2017-15994)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the rsync package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The receive_xattr function in xattrs.c in rsync 3.1.2     and 3.1.3-development does not check for a trailing     '\0' character in an xattr name, which allows remote     attackers to cause a denial of service (heap-based     buffer over-read and application crash) or possibly     have unspecified other impact by sending crafted data     to the daemon.(CVE-2017-16548)

  - The parse_arguments function in options.c in rsyncd in     rsync before 3.1.3 does not prevent multiple
    --protect-args uses, which allows remote attackers to     bypass an argument-sanitization protection     mechanism.(CVE-2018-5764)

  - The recv_files function in receiver.c in the daemon in     rsync 3.1.2, and 3.1.3-development before 2017-12-03,     proceeds with certain file metadata updates before     checking for a filename in the daemon_filter_list data     structure, which allows remote attackers to bypass     intended access restrictions.(CVE-2017-17433)

  - rsync 3.1.3-development before 2017-10-24 mishandles     archaic checksums, which makes it easier for remote     attackers to bypass intended access restrictions. NOTE:
    the rsync development branch has significant use beyond     the rsync developers, e.g., the code has been copied     for use in various GitHub projects.(CVE-2017-15994)
