CVE-2019-5747 | 2 Busybox, Canonical | 2 Busybox, Ubuntu Linux | 2025-06-09 | 7.5 High |
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-2019-20386 | 6 Canonical, Fedoraproject, Netapp and 3 more | 9 Ubuntu Linux, Fedora, Active Iq Unified Manager and 6 more | 2025-06-09 | 5.1 Medium |
An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur. | ||||
CVE-2019-12900 | 7 Bzip, Canonical, Debian and 4 more | 9 Bzip2, Ubuntu Linux, Debian Linux and 6 more | 2025-06-09 | 9.8 Critical |
BZ2_decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors. | ||||
CVE-2018-6954 | 3 Canonical, Opensuse, Systemd Project | 3 Ubuntu Linux, Leap, Systemd | 2025-06-09 | 7.8 High |
systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on. | ||||
CVE-2018-20679 | 2 Busybox, Canonical | 2 Busybox, Ubuntu Linux | 2025-06-09 | 7.5 High |
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-2018-15688 | 4 Canonical, Debian, Redhat and 1 more | 10 Ubuntu Linux, Debian Linux, Enterprise Linux and 7 more | 2025-06-09 | 8.8 High |
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239. | ||||
CVE-2018-15687 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2025-06-09 | 7.0 High |

CVE-2018-15686 | 5 Canonical, Debian, Oracle and 2 more | 10 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 7 more | 2025-06-09 | 7.8 High |
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239. | ||||
CVE-2018-1000517 | 3 Busybox, Canonical, Debian | 3 Busybox, Ubuntu Linux, Debian Linux | 2025-06-09 | 8 High |
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-2017-16544 | 5 Busybox, Canonical, Debian and 2 more | 8 Busybox, Ubuntu Linux, Debian Linux and 5 more | 2025-06-09 | 8.8 High |
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-2017-15873 | 3 Busybox, Canonical, Debian | 3 Busybox, Ubuntu Linux, Debian Linux | 2025-06-09 | 5.5 Medium |
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-2018-16864 | 5 Canonical, Debian, Oracle and 2 more | 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more | 2025-06-09 | 7.8 High |
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable. | ||||
CVE-2018-16865 | 5 Canonical, Debian, Oracle and 2 more | 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more | 2025-06-09 | 7.8 High |
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable. | ||||
CVE-2019-3843 | 5 Canonical, Fedoraproject, Netapp and 2 more | 9 Ubuntu Linux, Fedora, Cn1610 and 6 more | 2025-06-09 | 7.8 High |
It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled. | ||||
CVE-2019-3844 | 4 Canonical, Netapp, Redhat and 1 more | 8 Ubuntu Linux, Cn1610, Cn1610 Firmware and 5 more | 2025-06-09 | 7.8 High |
It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled. | ||||
CVE-2018-16866 | 5 Canonical, Debian, Netapp and 2 more | 26 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 23 more | 2025-06-09 | 3.3 Low |
An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable. | ||||

In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). | ||||
CVE-2019-5188 | 7 Canonical, Debian, E2fsprogs Project and 4 more | 10 Ubuntu Linux, Debian Linux, E2fsprogs and 7 more | 2025-05-30 | 7.5 High |
A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. |
