An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.
CVE-2018-20784 3 Canonical, Linux, Redhat 4 Ubuntu Linux, Linux Kernel, Enterprise Linux and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load.
CVE-2018-20781 3 Canonical, Gnome, Oracle 3 Ubuntu Linux, Gnome Keyring, Zfs Storage Appliance Kit 2024-11-21 2.1 LOW 7.8 HIGH
In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2, the user's password is kept in a session-child process spawned from the LightDM daemon. This can expose the credential in cleartext.

In GPAC 0.7.1 and earlier, gf_text_get_utf8_line in media_tools/text_import.c in libgpac_static.a allows an out-of-bounds write because of missing szLineConv bounds checking.
CVE-2018-20762 3 Canonical, Debian, Gpac Project 3 Ubuntu Linux, Debian Linux, Gpac 2024-11-21 6.8 MEDIUM 7.8 HIGH
GPAC version 0.7.1 and earlier has a buffer overflow vulnerability in the cat_multiple_files function in applications/mp4box/fileimport.c when MP4Box is used for a local directory containing crafted filenames.
CVE-2018-20761 3 Canonical, Debian, Gpac Project 3 Ubuntu Linux, Debian Linux, Gpac 2024-11-21 6.8 MEDIUM 7.8 HIGH
GPAC version 0.7.1 and earlier has a Buffer Overflow vulnerability in the gf_sm_load_init function in scene_manager.c in libgpac_static.a.
CVE-2018-20760 3 Canonical, Debian, Gpac 3 Ubuntu Linux, Debian Linux, Gpac 2024-11-21 6.8 MEDIUM 7.8 HIGH
In GPAC 0.7.1 and earlier, gf_text_get_utf8_line in media_tools/text_import.c in libgpac_static.a allows an out-of-bounds write because a certain -1 return value is mishandled.
CVE-2018-20750 4 Canonical, Debian, Libvnc Project and 1 more 15 Ubuntu Linux, Debian Linux, Libvncserver and 12 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
LibVNC through 0.9.12 contains a heap out-of-bounds write vulnerability in libvncserver/rfbserver.c. The fix for CVE-2018-15127 was incomplete.
CVE-2018-20749 4 Canonical, Debian, Libvnc Project and 1 more 15 Ubuntu Linux, Debian Linux, Libvncserver and 12 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
LibVNC before 0.9.12 contains a heap out-of-bounds write vulnerability in libvncserver/rfbserver.c. The fix for CVE-2018-15127 was incomplete.
CVE-2018-20748 4 Canonical, Debian, Libvnc Project and 1 more 15 Ubuntu Linux, Debian Linux, Libvncserver and 12 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
LibVNC before 0.9.12 contains multiple heap out-of-bounds write vulnerabilities in libvncclient/rfbproto.c. The fix for CVE-2018-20019 was incomplete.
CVE-2018-20685 9 Canonical, Debian, Fujitsu and 6 more 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more 2024-11-21 2.6 LOW 5.3 MEDIUM
In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.
CVE-2018-20669 3 Canonical, Linux, Netapp 7 Ubuntu Linux, Linux Kernel, Cn1610 and 4 more 2024-11-21 7.2 HIGH 7.8 HIGH
An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation.
CVE-2018-20662 5 Canonical, Debian, Fedoraproject and 2 more 11 Ubuntu Linux, Debian Linux, Fedora and 8 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.
CVE-2018-20650 4 Canonical, Debian, Freedesktop and 1 more 10 Ubuntu Linux, Debian Linux, Poppler and 7 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in FileSpec.cc) in pdfdetach.
CVE-2018-20615 4 Canonical, Haproxy, Opensuse and 1 more 5 Ubuntu Linux, Haproxy, Leap and 2 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.
CVE-2018-20551 2 Canonical, Freedesktop 2 Ubuntu Linux, Poppler 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
A reachable Object::getString assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to construction of invalid rich media annotation assets in the AnnotRichMedia class in Annot.c.
