Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3531-1 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)

- 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)

- 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)

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

Solution

Update the affected busybox and / or busybox-static packages.
