cpio 2.11, when using the --no-absolute-filenames option, allows local users to write to arbitrary files via a symlink attack on a file in an archive.

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

  - cpio 2.11, when using the --no-absolute-filenames option, allows local users to write to arbitrary files     via a symlink attack on a file in an archive. (CVE-2015-1197)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-557 advisory.

Sergey Poznyakoff reports :

This stable release fixes several potential vulnerabilities

CVE-2015-1197: cpio, when using the --no-absolute-filenames option, allows local users to write to arbitrary files via a symlink attack on a file in an archive.

CVE-2016-2037: The cpio_safer_name_suffix function in util.c allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted cpio file.

CVE-2019-14866: Improper input validation when writing tar header fields leads to unexpected tar generation.

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

  - GNU cpio copies files into or out of a cpio or tar     archive. Archives are files which contain a collection     of other files plus information about them, such as     their file name, owner, timestamps, and access     permissions. The archive can be another file on the     disk, a magnetic tape, or a pipe. GNU cpio supports the     following archive formats: binary, old ASCII, new     ASCII, crc, HPUX binary, HPUX old ASCII, old tar and     POSIX.1 tar. By default, cpio creates binary format     archives, so that they are compatible with older cpio     programs. When it is extracting files from archives,     cpio automatically recognizes which kind of archive it     is reading and can read archives created on machines     with a different byte-order.

  - Security Fix(es)

  - The cpio_safer_name_suffix function in util.c in cpio     2.11 allows remote attackers to cause a denial of     service (out-of-bounds write) via a crafted cpio     file.(CVE-2016-2037)

  - cpio 2.11, when using the --no-absolute-filenames     option, allows local users to write to arbitrary files     via a symlink attack on a file in an     archive.(CVE-2015-1197)

Alexander Cherepanov discovered that GNU cpio incorrectly handled symbolic links when used with the --no-absolute-filenames option. If a user or automated system were tricked into extracting a specially crafted cpio archive, a remote attacker could possibly use this issue to write arbitrary files. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-1197)

Gustavo Grieco discovered that GNU cpio incorrectly handled memory when extracting archive files. If a user or automated system were tricked into extracting a specially crafted cpio archive, a remote attacker could use this issue to cause GNU cpio to crash, resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2016-2037).

From the Debian Security Team :

Heap-based buffer overflow in the process_copy_in function in GNU Cpio 2.11 allows remote attackers to cause a denial of service via a large block value in a cpio archive.

cpio 2.11, when using the --no-absolute-filenames option, allows local users to write to arbitrary files via a symlink attack on a file in an archive.

Updated cpio package fixes security vulnerability :

In GNU Cpio 2.11, the --no-absolute-filenames option limits extracting contents of an archive to be strictly inside a current directory.
However, it can be bypassed with symlinks. While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory (CVE-2015-1197).

Updated cpio package fixes security vulnerabilities :

Heap-based buffer overflow in the process_copy_in function in GNU Cpio 2.11 allows remote attackers to cause a denial of service via a large block value in a cpio archive (CVE-2014-9112).

Additionally, a NULL pointer dereference in the copyin_link function which could cause a denial of service has also been fixed.

The remote host is affected by the vulnerability described in GLSA-201502-11 (GNU cpio: Multiple vulnerabilities)

    Two vulnerabilities have been discovered in GNU cpio:
      The list_file function in GNU cpio contains a heap-based buffer         overflow vulnerability (CVE-2014-9112)       A directory traversal vulnerability has been found in GNU cpio         (CVE-2015-1197)   Impact :

    A remote attacker may be able to entice a user to open a specially       crafted archive using GNU cpio, possibly resulting in execution of       arbitrary code, a Denial of Service condition, or overwriting arbitrary       files.
  Workaround :

    There is no known workaround at this time.
