The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0135-1 advisory.

  - Directory traversal vulnerability in the BusyBox implementation of tar before 1.22.0 v5 allows remote     attackers to point to files outside the current working directory via a symlink. (CVE-2011-5325)

  - huft_build in archival/libarchive/decompress_gunzip.c in BusyBox before 1.27.2 misuses a pointer, causing     segfaults and an application crash during an unzip operation on a specially crafted ZIP file.
    (CVE-2015-9261)

  - Integer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to cause a     denial of service (crash) via a malformed RFC1035-encoded domain name, which triggers an out-of-bounds     heap write. (CVE-2016-2147)

  - Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to     have unspecified impact via vectors involving OPTION_6RD parsing. (CVE-2016-2148)

  - The recv_and_process_client_pkt function in networking/ntpd.c in busybox allows remote attackers to cause     a denial of service (CPU and bandwidth consumption) via a forged NTP packet, which triggers a     communication loop. (CVE-2016-6301)

  - The get_next_block function in archival/libarchive/decompress_bunzip2.c in BusyBox 1.27.2 has an Integer     Overflow that may lead to a write access violation. (CVE-2017-15873)

  - archival/libarchive/decompress_unlzma.c in BusyBox 1.27.2 has an Integer Underflow that leads to a read     access violation. (CVE-2017-15874)

  - In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of     the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in     executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary     file writes, or other attacks. (CVE-2017-16544)

  - Busybox contains a Missing SSL certificate validation vulnerability in The busybox wget applet that can     result in arbitrary code execution. This attack appear to be exploitable via Simply download any file over     HTTPS using busybox wget https://compromised-domain.com/important-file. (CVE-2018-1000500)

  - BusyBox project BusyBox wget version prior to commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e contains a     Buffer Overflow vulnerability in Busybox wget that can result in heap buffer overflow. This attack appear     to be exploitable via network connectivity. This vulnerability appears to have been fixed in after commit     8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e. (CVE-2018-1000517)

  - An issue was discovered in BusyBox before 1.30.0. An out of bounds read in udhcp components (consumed by     the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack     by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in     networking/udhcp/common.c that 4-byte options are indeed 4 bytes. (CVE-2018-20679)

  - An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by     the DHCP server, client, and/or relay) might allow a remote attacker to leak sensitive information from     the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding     DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679. (CVE-2019-5747)

  - decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer,     with a resultant invalid free or segmentation fault, via malformed gzip data. (CVE-2021-28831)

  - A NULL pointer dereference in Busybox's man applet leads to denial of service when a section name is     supplied but no page argument is given (CVE-2021-42373)

  - An out-of-bounds heap read in Busybox's unlzma applet leads to information leak and denial of service when     crafted LZMA-compressed input is decompressed. This can be triggered by any applet/format that     (CVE-2021-42374)

  - An incorrect handling of a special element in Busybox's ash applet leads to denial of service when     processing a crafted shell command, due to the shell mistaking specific characters for reserved     characters. This may be used for DoS under rare conditions of filtered command input. (CVE-2021-42375)

  - A NULL pointer dereference in Busybox's hush applet leads to denial of service when processing a crafted     shell command, due to missing validation after a \x03 delimiter character. This may be used for DoS under     very rare conditions of filtered command input. (CVE-2021-42376)

  - An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code     execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may     be used for remote code execution under rare conditions of filtered command input. (CVE-2021-42377)

  - A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when     processing a crafted awk pattern in the getvar_i function (CVE-2021-42378)

Busybox, utility programs for small and embedded systems, was affected by several security vulnerabilities. The Common Vulnerabilities and Exposures project identifies the following issues.

CVE-2011-5325

A path traversal vulnerability was found in Busybox implementation of tar. tar will extract a symlink that points outside of the current working directory and then follow that symlink when extracting other files. This allows for a directory traversal attack when extracting untrusted tarballs.

CVE-2013-1813

When device node or symlink in /dev should be created inside 2-or-deeper subdirectory (/dev/dir1/dir2.../node), the intermediate directories are created with incorrect permissions.

CVE-2014-4607

An integer overflow may occur when processing any variant of a 'literal run' in the lzo1x_decompress_safe function. Each of these three locations is subject to an integer overflow when processing zero bytes. This exposes the code that copies literals to memory corruption.

CVE-2014-9645

The add_probe function in modutils/modprobe.c in BusyBox allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an 'ifconfig /usbserial up' command or a 'mount -t /snd_pcm none /' command.

CVE-2016-2147

Integer overflow in the DHCP client (udhcpc) in BusyBox allows remote attackers to cause a denial of service (crash) via a malformed RFC1035-encoded domain name, which triggers an out-of-bounds heap write.

CVE-2016-2148

Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox allows remote attackers to have unspecified impact via vectors involving OPTION_6RD parsing.

CVE-2017-15873

The get_next_block function in archival/libarchive /decompress_bunzip2.c in BusyBox has an Integer Overflow that may lead to a write access violation.

CVE-2017-16544

In the add_match function in libbb/lineedit.c in BusyBox, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.

CVE-2018-1000517

BusyBox contains a Buffer Overflow vulnerability in Busybox wget that can result in a heap-based buffer overflow. This attack appears to be exploitable via network connectivity.

CVE-2015-9621

Unziping a specially crafted zip file results in a computation of an invalid pointer and a crash reading an invalid address.

For Debian 9 stretch, these problems have been fixed in version 1:1.22.0-19+deb9u1.

We recommend that you upgrade your busybox packages.

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3935-1 advisory.

    Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar archives. If a user or     automated system were tricked into processing a specially crafted tar archive, a remote attacker could     overwrite arbitrary files outside of the current directory. This issue only affected Ubuntu 14.04 LTS and     Ubuntu 16.04 LTS. (CVE-2011-5325)

    Mathias Krause discovered that BusyBox incorrectly handled kernel module loading restrictions. A local     attacker could possibly use this issue to bypass intended restrictions. This issue only affected Ubuntu     14.04 LTS. (CVE-2014-9645)

    It was discovered that BusyBox incorrectly handled certain ZIP archives. If a user or automated system     were tricked into processing a specially crafted ZIP archive, a remote attacker could cause BusyBox to     crash, leading to a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2015-9261)

    Nico Golde discovered that the BusyBox DHCP client incorrectly handled certain malformed domain names. A     remote attacker could possibly use this issue to cause the DHCP client to crash, leading to a denial of     service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-2147)

    Nico Golde discovered that the BusyBox DHCP client incorrectly handled certain 6RD options. A remote     attacker could use this issue to cause the DHCP client to crash, leading to a denial of service, or     possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2016-2148)

    It was discovered that BusyBox incorrectly handled certain bzip2 archives. If a user or automated system     were tricked into processing a specially crafted bzip2 archive, a remote attacker could cause BusyBox to     crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu     14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-15873)

    It was discovered that BusyBox incorrectly handled tab completion. A local attacker could possibly use     this issue to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2017-16544)

    It was discovered that the BusyBox wget utility incorrectly handled certain responses. A remote attacker     could use this issue to cause BusyBox to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2018-1000517)

    It was discovered that the BusyBox DHCP utilities incorrectly handled certain memory operations. A remote     attacker could possibly use this issue to access sensitive information. (CVE-2018-20679, CVE-2019-5747)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote host is affected by the vulnerability described in GLSA-201612-04 (BusyBox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in BusyBox. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time. However, on Gentoo, the       remote code execution vulnerability can be avoided if you don&rsquo;t use       BusyBox&rsquo;s udhcpc or build the package without the &ldquo;ipv6&rdquo; USE flag       enabled.
