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.
CVE-2018-16645 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
There is an excessive memory allocation issue in the functions ReadBMPImage of coders/bmp.c and ReadDIBImage of coders/dib.c in ImageMagick 7.0.8-11, which allows remote attackers to cause a denial of service via a crafted image file.
CVE-2018-16644 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
There is a missing check for length in the functions ReadDCMImage of coders/dcm.c and ReadPICTImage of coders/pict.c in ImageMagick 7.0.8-11, which allows remote attackers to cause a denial of service via a crafted image.
CVE-2018-16643 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
The functions ReadDCMImage in coders/dcm.c, ReadPWPImage in coders/pwp.c, ReadCALSImage in coders/cals.c, and ReadPICTImage in coders/pict.c in ImageMagick 7.0.8-4 do not check the return value of the fputc function, which allows remote attackers to cause a denial of service via a crafted image file.
CVE-2018-16642 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
The function InsertRow in coders/cut.c in ImageMagick 7.0.7-37 allows remote attackers to cause a denial of service via a crafted image file due to an out-of-bounds write.
CVE-2018-16640 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.8-5 has a memory leak vulnerability in the function ReadOneJNGImage in coders/png.c.
CVE-2018-16585 3 Artifex, Canonical, Debian 3 Ghostscript, Ubuntu Linux, Debian Linux 2024-11-21 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact. Note: A reputable source believes that the CVE is potentially a duplicate of CVE-2018-15910 as explained in Red Hat bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1626193)
CVE-2018-16543 3 Artifex, Canonical, Debian 3 Ghostscript, Ubuntu Linux, Debian Linux 2024-11-21 6.8 MEDIUM 7.8 HIGH
In Artifex Ghostscript before 9.24, gssetresolution and gsgetresolution allow attackers to have an unspecified impact.
