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.

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

  - 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)

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

The remote Debian 9 host has a package installed that is affected by a vulnerability as referenced in the dla-2833 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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)

According to the versions of the rsync package installed, the EulerOS Virtualization for ARM 64 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)

Trail of Bits used the automated vulnerability discovery tools developed for the DARPA Cyber Grand Challenge to audit zlib. As rsync, a fast, versatile, remote (and local) file-copying tool, uses an embedded copy of zlib, those issues are also present in rsync.

CVE-2016-9840 In order to avoid undefined behavior, remove offset pointer optimization, as this is not compliant with the C standard.

CVE-2016-9841 Only use post-increment to be compliant with the C standard.

CVE-2016-9842 In order to avoid undefined behavior, do not shift negative values, as this is not compliant with the C standard.

CVE-2016-9843 In order to avoid undefined behavior, do not pre-decrement a pointer in big-endian CRC calculation, as this is not compliant with the C standard.

CVE-2018-5764 Prevent remote attackers from being able to bypass the argument-sanitization protection mechanism by ignoring --protect-args when already sent by client.

For Debian 8 'Jessie', these problems have been fixed in version 3.1.1-3+deb8u2.

We recommend that you upgrade your rsync packages.

An update of the rsync package has been released.

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

  - The daemon in rsync 3.1.2, and 3.1.3-development before     2017-12-03, does not check for fnamecmp filenames in     the daemon_filter_list data structure (in the     recv_files function in receiver.c) and also does not     apply the sanitize_paths protection mechanism to     pathnames found in 'xname follows' strings (in the     read_ndx_and_attrs function in rsync.c), which allows     remote attackers to bypass intended access     restrictions.(CVE-2017-17434)
