CVE-2018-6789 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2021-06-03 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely.
CVE-2019-8912 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2021-06-02 7.2 HIGH 7.8 HIGH
In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.
CVE-2019-8980 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2021-06-02 7.8 HIGH 7.5 HIGH
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.
CVE-2019-9003 4 Canonical, Linux, Netapp and 1 more 8 Ubuntu Linux, Linux Kernel, Cn1610 and 5 more 2021-06-02 7.8 HIGH 7.5 HIGH
In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop.
CVE-2018-20784 3 Canonical, Linux, Redhat 4 Ubuntu Linux, Linux Kernel, Enterprise Linux and 1 more 2021-06-02 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-2019-15538 6 Canonical, Debian, Fedoraproject and 3 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2021-06-02 7.8 HIGH 7.5 HIGH
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.
CVE-2017-8831 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2021-06-01 6.9 MEDIUM 6.4 MEDIUM
The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5 allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a "double fetch" vulnerability.
CVE-2019-14907 5 Canonical, Fedoraproject, Redhat and 2 more 9 Ubuntu Linux, Fedora, Enterprise Linux and 6 more 2021-05-29 2.6 LOW 6.5 MEDIUM
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).
CVE-2019-1000018 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-05-28 4.6 MEDIUM 7.8 HIGH
rssh version 2.3.4 contains a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in allowscp permission that can result in Local command execution. This attack appear to be exploitable via An authorized SSH user with the allowscp permission.
CVE-2018-16435 4 Canonical, Debian, Littlecms and 1 more 6 Ubuntu Linux, Debian Linux, Little Cms Color Engine and 3 more 2021-05-26 4.3 MEDIUM 5.5 MEDIUM
Little CMS (aka Little Color Management System) 2.9 has an integer overflow in the AllocateDataSet function in cmscgats.c, leading to a heap-based buffer overflow in the SetData function via a crafted file in the second argument to cmsIT8LoadFromFile.
CVE-2019-18978 3 Canonical, Debian, Rack-cors Project 3 Ubuntu Linux, Debian Linux, Rack-cors 2021-05-21 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in the rack-cors (aka Rack CORS Middleware) gem before 1.0.4 for Ruby. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format.
CVE-2021-3492 1 Canonical 1 Ubuntu Linux 2021-05-21 7.2 HIGH 7.8 HIGH
Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562.
CVE-2018-10811 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-05-18 5.0 MEDIUM 7.5 HIGH
strongSwan 5.6.0 and older allows Remote Denial of Service because of Missing Initialization of a Variable.
CVE-2007-4476 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Tar 2021-05-17 7.5 HIGH N/A
Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack."
CVE-2008-4539 4 Canonical, Debian, Kvm Qumranet and 1 more 4 Ubuntu Linux, Debian Linux, Kvm and 1 more 2021-05-14 7.2 HIGH N/A
Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue exists because of an incorrect fix for CVE-2007-1320.
CVE-2018-10196 3 Canonical, Fedoraproject, Graphviz 3 Ubuntu Linux, Fedora, Graphviz 2021-05-13 4.3 MEDIUM 5.5 MEDIUM
NULL pointer dereference vulnerability in the rebuild_vlists function in lib/dotgen/conc.c in the dotgen library in Graphviz 2.40.1 allows remote attackers to cause a denial of service (application crash) via a crafted file.
CVE-2020-14375 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2021-05-05 4.4 MEDIUM 7.8 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhost_crypto has validated it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-1935 6 Apache, Canonical, Debian and 3 more 20 Tomcat, Ubuntu Linux, Debian Linux and 17 more 2021-05-04 5.8 MEDIUM 4.8 MEDIUM
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
CVE-2020-15706 6 Canonical, Debian, Gnu and 3 more 13 Ubuntu Linux, Debian Linux, Grub2 and 10 more 2021-04-30 4.4 MEDIUM 6.4 MEDIUM
GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2018-16323 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2021-04-28 4.3 MEDIUM 6.5 MEDIUM
ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data.
