The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4253-1 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)

  - The add_probe function in modutils/modprobe.c in BusyBox before 1.23.0 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-2014-9645)

  - 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)

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 client, server, 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)
