CVE-2018-15126 3 Canonical, Debian, Libvnc Project 3 Ubuntu Linux, Debian Linux, Libvncserver 2026-06-17 7.5 HIGH 9.8 CRITICAL
LibVNC before commit 73cb96fec028a576a5a24417b57723b55854ad7b contains heap use-after-free vulnerability in server code of file transfer extension that can result remote code execution
CVE-2018-15120 2 Canonical, Gnome 2 Ubuntu Linux, Pango 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
libpango in Pango 1.40.8 through 1.42.3, as used in hexchat and other products, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted text with invalid Unicode sequences.
CVE-2018-14938 2 Canonical, Digitalcorpora 2 Ubuntu Linux, Tcpflow 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in wifipcap/wifipcap.cpp in TCPFLOW through 1.5.0-alpha. There is an integer overflow in the function handle_prism during caplen processing. If the caplen is less than 144, one can cause an integer overflow in the function handle_80211, which will result in an out-of-bounds read and may allow access to sensitive memory (or a denial of service).
CVE-2018-14883 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before 7.2.8. An Integer Overflow leads to a heap-based buffer over-read in exif_thumbnail_extract of exif.c.
CVE-2018-14851 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
exif_process_IFD_in_MAKERNOTE in ext/exif/exif.c in PHP before 5.6.37, 7.0.x before 7.0.31, 7.1.x before 7.1.20, and 7.2.x before 7.2.8 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG file.
CVE-2018-14734 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2026-06-17 6.1 MEDIUM 7.8 HIGH
drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allows attackers to cause a denial of service (use-after-free).
CVE-2018-14682 5 Cabextract, Cabextract Project, Canonical and 2 more 8 Libmspack, Cabextract, Ubuntu Linux and 5 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the TOLOWER() macro for CHM decompression.
CVE-2018-14681 5 Cabextract, Cabextract Project, Canonical and 2 more 8 Libmspack, Cabextract, Ubuntu Linux and 5 more 2026-06-17 6.8 MEDIUM 8.8 HIGH
An issue was discovered in kwajd_read_headers in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file header extensions could cause a one or two byte overwrite.
CVE-2018-14680 5 Cabextract, Cabextract Project, Canonical and 2 more 8 Libmspack, Cabextract, Ubuntu Linux and 5 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM

An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the CHM PMGI/PMGL chunk number validity checks, which could lead to denial of service (uninitialized data dereference and application crash).
CVE-2018-14678 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2026-06-17 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges.
CVE-2018-14665 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2026-06-17 7.2 HIGH 6.6 MEDIUM
A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
CVE-2018-14662 4 Canonical, Debian, Opensuse and 1 more 6 Ubuntu Linux, Debian Linux, Leap and 3 more 2026-06-17 2.7 LOW 5.7 MEDIUM
It was found Ceph versions before 13.2.4 that authenticated ceph users with read only permissions could steal dm-crypt encryption keys used in ceph disk encryption.
CVE-2018-14645 3 Canonical, Haproxy, Redhat 5 Ubuntu Linux, Haproxy, Enterprise Linux and 2 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
A flaw was discovered in the HPACK decoder of HAProxy, before 1.8.14, that is used for HTTP/2. An out-of-bounds read access in hpack_valid_idx() resulted in a remote crash and denial of service.
CVE-2018-14634 6 Canonical, F5, Linux and 3 more 28 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 25 more 2026-06-17 7.2 HIGH 7.8 HIGH
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.
CVE-2018-14633 4 Canonical, Debian, Linux and 1 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2026-06-17 8.3 HIGH 7.0 HIGH
A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.
CVE-2018-14629 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service.
CVE-2018-14625 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2026-06-17 4.4 MEDIUM 5.3 MEDIUM
A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients.
CVE-2018-14622 4 Canonical, Debian, Libtirpc Project and 1 more 8 Ubuntu Linux, Debian Linux, Libtirpc and 5 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections.
CVE-2018-14618 4 Canonical, Debian, Haxx and 1 more 4 Ubuntu Linux, Debian Linux, Libcurl and 1 more 2026-06-17 10.0 HIGH 7.5 HIGH
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)
