CVE-2021-30499 [HIGH] CWE-119 CVE-2021-30499: A flaw was found in libcaca. A buffer overflow of export.c in function export_troff might lead to me A flaw was found in libcaca. A buffer overflow of export.c in function export_troff might lead to memory corruption and other potential consequences.

CVE-2021-30465 [HIGH] CWE-362 CVE-2021-30465: runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit th runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal. To exploit the vulnerability, an attacker must be able to create multiple containers with a fairly specific mount configuration. The problem occurs via a symlink-exchange attack that relies on a race condition.

CVE-2021-30500 [HIGH] CWE-476 CVE-2021-30500: Null pointer dereference was found in upx PackLinuxElf::canUnpack() in p_lx_elf.cpp,in version UPX 4 Null pointer dereference was found in upx PackLinuxElf::canUnpack() in p_lx_elf.cpp,in version UPX 4.0.0. That allow attackers to execute arbitrary code and cause a denial of service via a crafted file.

CVE-2021-33200 [HIGH] CWE-787 CVE-2021-33200: kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arith kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction chan

CVE-2021-28651 [HIGH] CWE-401 CVE-2021-28651: An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, i An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.

CVE-2021-30501 [MEDIUM] CWE-20 CVE-2021-30501: An assertion abort was found in upx MemBuffer::alloc() in mem.cpp, in version UPX 4.0.0. The flow al An assertion abort was found in upx MemBuffer::alloc() in mem.cpp, in version UPX 4.0.0. The flow allows attackers to cause a denial of service (abort) via a crafted file.

CVE-2021-31525 [MEDIUM] CWE-674 CVE-2021-31525: net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of service (panic) via a large header to ReadRequest or ReadResponse. Server, Transport, and Client can each be affected in some configurations.

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-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-2021-33194 [HIGH] CWE-835 CVE-2021-33194: golang.org/x/net before v0.0.0-20210520170846-37e1c6afe023 allows attackers to cause a denial of ser golang.org/x/net before v0.0.0-20210520170846-37e1c6afe023 allows attackers to cause a denial of service (infinite loop) via crafted ParseFragment input.
