CVE-2018-1049 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.
CVE-2018-19215 2 Nasm, Redhat 2 Netwide Assembler, Enterprise Linux 2026-06-17 6.8 MEDIUM 7.8 HIGH
Netwide Assembler (NASM) 2.14rc16 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for the special cases of the % and $ and ! characters.
CVE-2018-19214 2 Nasm, Redhat 2 Netwide Assembler, Enterprise Linux 2026-06-17 6.8 MEDIUM 7.8 HIGH
Netwide Assembler (NASM) 2.14rc15 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for insufficient input.
CVE-2018-19208 3 Libwpd Project, Redhat, Suse 3 Libwpd, Enterprise Linux, Suse Linux Enterprise Server 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
In libwpd 0.10.2, there is a NULL pointer dereference in the function WP6ContentListener::defineTable in WP6ContentListener.cpp that will lead to a denial of service attack. This is related to WPXTable.h.
CVE-2018-18897 4 Canonical, Debian, Freedesktop and 1 more 10 Ubuntu Linux, Debian Linux, Poppler and 7 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo.
CVE-2018-18751 3 Canonical, Gnu, Redhat 3 Ubuntu Linux, Gettext, Enterprise Linux 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in GNU gettext 0.19.8. There is a double free in default_add_message in read-catalog.c, related to an invalid free in po_gram_parse in po-gram-gen.y, as demonstrated by lt-msgfmt.
CVE-2018-18584 7 Cabextract Project, Canonical, Debian and 4 more 7 Cabextract, Ubuntu Linux, Debian Linux and 4 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
In mspack/cab.h in libmspack before 0.8alpha and cabextract before 1.8, the CAB block input buffer is one byte too small for the maximal Quantum block, leading to an out-of-bounds write.
CVE-2018-18506 5 Canonical, Debian, Mozilla and 2 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.
CVE-2018-18438 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2026-06-17 2.1 LOW 5.5 MEDIUM
Qemu has integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value.
CVE-2018-18314 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-18313 6 Apple, Canonical, Debian and 3 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.
CVE-2018-18312 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-18311 8 Apple, Canonical, Debian and 5 more 18 Mac Os X, Ubuntu Linux, Debian Linux and 15 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-17958 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
CVE-2018-17456 4 Canonical, Debian, Git-scm and 1 more 11 Ubuntu Linux, Debian Linux, Git and 8 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Git before 2.14.5, 2.15.x before 2.15.3, 2.16.x before 2.16.5, 2.17.x before 2.17.2, 2.18.x before 2.18.1, and 2.19.x before 2.19.1 allows remote code execution during processing of a recursive "git clone" of a superproject if a .gitmodules file has a URL field beginning with a '-' character.
CVE-2018-17189 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.
CVE-2018-16890 8 Canonical, Debian, F5 and 5 more 10 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 7 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2018-16888 4 Canonical, Netapp, Redhat and 1 more 5 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 2 more 2026-06-17 1.9 LOW 4.7 MEDIUM
It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.
CVE-2018-16884 4 Canonical, Debian, Linux and 1 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2026-06-17 6.7 MEDIUM 8.0 HIGH
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.
CVE-2018-16881 3 Debian, Redhat, Rsyslog 13 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 10 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable.
