CVE-2018-16876 4 Canonical, Debian, Redhat and 1 more 10 Ubuntu Linux, Debian Linux, Ansible and 7 more 2021-08-04 3.5 LOW 5.3 MEDIUM
ansible before versions 2.5.14, 2.6.11, 2.7.5 is vulnerable to a information disclosure flaw in vvv+ mode with no_log on that can lead to leakage of sensible data.
CVE-2018-17205 3 Canonical, Openvswitch, Redhat 3 Ubuntu Linux, Openvswitch, Openstack 2021-08-04 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting ofproto_rule_insert__ in ofproto/ofproto.c. During bundle commit, flows that are added in a bundle are applied to ofproto in order. If a flow cannot be added (e.g., the flow action is a go-to for a group id that does not exist), OvS tries to revert back all previous flows that were successfully applied from the same bundle. This is possible since OvS maintains list of old flows that were replaced by flows from the bundle. While reinserting old flows, OvS has an assertion failure due to a check on rule state != RULE_INITIALIZED. This would work for new flows, but for an old flow the rule state is RULE_REMOVED. The assertion failure causes an OvS crash.
CVE-2018-17204 4 Canonical, Debian, Openvswitch and 1 more 4 Ubuntu Linux, Debian Linux, Openvswitch and 1 more 2021-08-04 4.0 MEDIUM 4.3 MEDIUM
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.
CVE-2018-10875 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Ansible Engine and 8 more 2021-08-04 4.6 MEDIUM 7.8 HIGH
A flaw was found in ansible. ansible.cfg is read from the current working directory which can be altered to make it point to a plugin or a module path under the control of an attacker, thus allowing the attacker to execute arbitrary code.
CVE-2018-10915 4 Canonical, Debian, Postgresql and 1 more 9 Ubuntu Linux, Debian Linux, Postgresql and 6 more 2021-08-04 6.0 MEDIUM 7.5 HIGH
A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction. Postgresql versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 are affected.
CVE-2018-10903 3 Canonical, Cryptography, Redhat 3 Ubuntu Linux, Python-cryptography, Openstack 2021-08-04 5.0 MEDIUM 7.5 HIGH
A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage.
CVE-2018-10855 3 Canonical, Debian, Redhat 6 Ubuntu Linux, Debian Linux, Ansible Engine and 3 more 2021-08-04 4.3 MEDIUM 5.9 MEDIUM
Ansible 2.5 prior to 2.5.5, and 2.4 prior to 2.4.5, do not honor the no_log task flag for failed tasks. When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.
CVE-2018-17963 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2021-08-04 7.5 HIGH 9.8 CRITICAL
qemu_deliver_packet_iov in net/net.c in Qemu accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact.
CVE-2018-1000808 3 Canonical, Pyopenssl Project, Redhat 7 Ubuntu Linux, Pyopenssl, Enterprise Linux Desktop and 4 more 2021-08-04 4.3 MEDIUM 5.9 MEDIUM
Python Cryptographic Authority pyopenssl version Before 17.5.0 contains a CWE - 401 : Failure to Release Memory Before Removing Last Reference vulnerability in PKCS #12 Store that can result in Denial of service if memory runs low or is exhausted. This attack appear to be exploitable via Depends upon calling application, however it could be as simple as initiating a TLS connection. Anything that would cause the calling application to reload certificates from a PKCS #12 store.. This vulnerability appears to have been fixed in 17.5.0.
CVE-2018-17206 4 Canonical, Debian, Openvswitch and 1 more 4 Ubuntu Linux, Debian Linux, Openvswitch and 1 more 2021-08-04 4.0 MEDIUM 4.9 MEDIUM
An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6. The decode_bundle function inside lib/ofp-actions.c is affected by a buffer over-read issue during BUNDLE action decoding.
CVE-2019-17544 2 Canonical, Gnu 2 Ubuntu Linux, Aspell 2021-08-02 6.4 MEDIUM 9.1 CRITICAL
libaspell.a in GNU Aspell before 0.60.8 has a stack-based buffer over-read in acommon::unescape in common/getdata.cpp via an isolated \ character.
CVE-2019-11815 5 Canonical, Debian, Linux and 2 more 15 Ubuntu Linux, Debian Linux, Linux Kernel and 12 more 2021-07-21 9.3 HIGH 8.1 HIGH
An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8. There is a race condition leading to a use-after-free, related to net namespace cleanup.
CVE-2019-12521 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-07-21 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.
CVE-2019-17542 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2021-07-21 7.5 HIGH 9.8 CRITICAL
FFmpeg before 4.2 has a heap-based buffer overflow in vqa_decode_chunk because of an out-of-array access in vqa_decode_init in libavcodec/vqavideo.c.
CVE-2020-5963 2 Canonical, Nvidia 9 Ubuntu Linux, Geforce, Geforce Firmware and 6 more 2021-07-21 4.6 MEDIUM 7.8 HIGH
NVIDIA Windows GPU Display Driver, all versions, contains a vulnerability in the Inter Process Communication APIs, in which improper access control may lead to code execution, denial of service, or information disclosure.
CVE-2020-5973 2 Canonical, Nvidia 2 Ubuntu Linux, Virtual Gpu 2021-07-21 2.1 LOW 4.4 MEDIUM
NVIDIA Virtual GPU Manager and the guest drivers contain a vulnerability in vGPU plugin, in which there is the potential to execute privileged operations, which may lead to denial of service. This affects vGPU version 8.x (prior to 8.4), version 9.x (prior to 9.4) and version 10.x (prior to 10.3).
CVE-2019-20908 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2021-07-21 6.9 MEDIUM 6.7 MEDIUM
An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032.
CVE-2020-8517 3 Canonical, Opensuse, Squid-cache 3 Ubuntu Linux, Leap, Squid 2021-07-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
CVE-2020-2583 7 Canonical, Debian, Mcafee and 4 more 24 Ubuntu Linux, Debian Linux, Epolicy Orchestrator and 21 more 2021-07-21 4.3 MEDIUM 3.7 LOW

Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
CVE-2019-15031 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2021-07-21 3.6 LOW 4.4 MEDIUM
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.
