CVE-2018-16866 5 Canonical, Debian, Netapp and 2 more 21 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 18 more 2024-11-21 2.1 LOW 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.
CVE-2018-16865 5 Canonical, Debian, Oracle and 2 more 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more 2024-11-21 4.6 MEDIUM 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-2018-16864 5 Canonical, Debian, Oracle and 2 more 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more 2024-11-21 4.6 MEDIUM 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-2018-16862 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 2.1 LOW 5.3 MEDIUM
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.
CVE-2018-16851 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service.
CVE-2018-16850 3 Canonical, Postgresql, Redhat 3 Ubuntu Linux, Postgresql, Enterprise Linux 2024-11-21 7.5 HIGH 9.8 CRITICAL
postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER ... REFERENCING. Using a purpose-crafted trigger definition, an attacker can cause arbitrary SQL statements to run, with superuser privileges.
CVE-2018-16847 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2024-11-21 4.6 MEDIUM 7.8 HIGH
An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process.
CVE-2018-16846 4 Canonical, Debian, Opensuse and 1 more 6 Ubuntu Linux, Debian Linux, Leap and 3 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
It was found in Ceph versions before 13.2.4 that authenticated ceph RGW users can cause a denial of service against OMAPs holding bucket indices.
CVE-2018-16845 5 Apple, Canonical, Debian and 2 more 5 Xcode, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 5.8 MEDIUM 6.1 MEDIUM
nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
CVE-2018-16844 4 Apple, Canonical, Debian and 1 more 4 Xcode, Ubuntu Linux, Debian Linux and 1 more 2024-11-21 7.8 HIGH 7.5 HIGH
nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.
CVE-2018-16843 5 Apple, Canonical, Debian and 2 more 5 Xcode, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 7.8 HIGH 7.5 HIGH
nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.
CVE-2018-16842 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2024-11-21 6.4 MEDIUM 4.4 MEDIUM
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.
CVE-2018-16841 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process.
CVE-2018-16840 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2024-11-21 7.5 HIGH 4.3 MEDIUM
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
CVE-2018-16839 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Curl 2024-11-21 7.5 HIGH 4.3 MEDIUM
Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.
CVE-2018-16802 4 Artifex, Canonical, Debian and 1 more 9 Ghostscript, Ubuntu Linux, Debian Linux and 6 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509.
CVE-2018-16750 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
In ImageMagick 7.0.7-29 and earlier, a memory leak in the formatIPTCfromBuffer function in coders/meta.c was found.
CVE-2018-16749 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
In ImageMagick 7.0.7-29 and earlier, a missing NULL check in ReadOneJNGImage in coders/png.c allows an attacker to cause a denial of service (WriteBlob assertion failure and application exit) via a crafted file.
CVE-2018-16658 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 3.6 LOW 6.1 MEDIUM
An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940.
CVE-2018-16646 3 Canonical, Debian, Freedesktop 3 Ubuntu Linux, Debian Linux, Poppler 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
In Poppler 0.68.0, the Parser::getObj() function in Parser.cc may cause infinite recursion via a crafted file. A remote attacker can leverage this for a DoS attack.
