CVE-2020-10729 [MEDIUM] CWE-330 CVE-2020-10729: A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansi

CVE-2021-28652 [MEDIUM] CWE-401 CVE-2021-28652: An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validatio An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cach

CVE-2021-31808 [MEDIUM] CWE-190 CVE-2021-31808: An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, i An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this.

CVE-2021-31806 [MEDIUM] CWE-116 CVE-2021-31806: An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, i An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request processing.

CVE-2021-28662 [MEDIUM] CWE-116 CVE-2021-28662: An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a ce An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic.

CVE-2020-25668 [HIGH] CWE-362 CVE-2020-25668: A flaw was found in Linux Kernel because access to the global variable fg_console is not properly sy A flaw was found in Linux Kernel because access to the global variable fg_console is not properly synchronized leading to a use after free in con_font_op.

CVE-2021-22543 [HIGH] CWE-119 CVE-2021-22543: An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can b An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation.

CVE-2020-22015 [HIGH] CWE-120 CVE-2020-22015: Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to the out of bounds in libav Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to the out of bounds in libavformat/movenc.c, which could let a remote malicious user obtain sensitive information, cause a Denial of Service, or execute arbitrary code.

CVE-2020-27815 [HIGH] CWE-119 CVE-2020-27815: A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with t A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

CVE-2021-25217 [HIGH] CWE-119 CVE-2021-25217: In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., re In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no longer supported by ISC. From inspection it is clear that the defect is also present in releases from those series, but they have not been of
