CVE Vulnerability Catalog

An improper access control vulnerability in AMD Secure Encrypted Virtualization (SEV) firmware allows a malicious hypervisor to bypass RMP protections, potentially compromising SEV-SNP guest memory integrity.

An issue was discovered in py-lmdb 0.97 where for certain values of mn_flags, mdb_cursor_set triggers a memcpy with an invalid write operation within mdb_xcursor_init1. This occurs when accessing a data.mdb file supplied by an attacker.

A NULL pointer dereference vulnerability was found in the Linux kernel's ALSA driver for the TASCAM US-144MKII device. A malicious USB device can have a configuration with interface number 1 but missing interface 0, leading to a system crash.

A vulnerability in the Nokogiri library affects the `Nokogiri::XML::NodeSet#[]` method (and its alias `#slice`). The index check against the node set's bounds used a 32-bit-truncated copy of the index, allowing a large negative index to pass the check and then be used at full width, reading outside the node set's storage.

An issue was discovered in py-lmdb 0.97 where mdb_page_touch does not properly set up mc->mc_pg[mc->top] for certain mp_flags values, leading to an invalid write operation. The vulnerability can be triggered by supplying a crafted data.mdb file.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware allows a privileged attacker to modify the lock bit, potentially downgrading the firmware and compromising system integrity.

Insufficient granularity of access control in SEV firmware allows a privileged user with a malicious hypervisor to create a SEV-ES guest with an ASID meant for SEV-SNP guests, potentially leading to partial loss of confidentiality.

The email module in Python, specifically the BytesGenerator class, improperly quotes newlines in email headers during serialization, allowing header injection. This only affects usage of LiteralHeader that does not respect email folding.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware causes insufficient or incomplete data removal in a hardware component, resulting in incomplete IOMMU flushing. This can potentially lead to a loss of confidentiality and integrity in guest memory.

In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.

A use-after-free vulnerability in SEV firmware allows a malicious hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent, potentially leading to loss of integrity.

A vulnerability in the UEFI implementation within QEMU (or similar software) causes a heap overflow in the hardware module (hw/uefi). An attacker can exploit this flaw to gain unauthorized access or execute arbitrary code.

A vulnerability in Linux PAM before version 1.6.0 allows attackers to cause a denial of service by blocking the login process. The issue stems from the lack of the O_DIRECTORY flag in the openat call for the protect_dir function, enabling the use of mkfifo.

In the Linux kernel, a vulnerability in the mshv_vtl component occurs when registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, where the computed vmemmap_shift may exceed MAX_FOLIO_ORDER, leading to incorrect behavior.

A vulnerability in the Linux kernel's FUSE filesystem causes a hang during sync initialization when the FUSE server exits (e.g., due to error or crash) while processing the FUSE_INIT request. The issue stems from the lack of abort on a fatal signal, blocking filesystem creation.

The golang.org/x/crypto/openpgp package is unsafe by design, has numerous known security issues, is not maintained, and should not be used. It is recommended to use the maintained package github.com/ProtonMail/go-crypto/openpgp instead.

Granian is a Rust HTTP server for Python applications. From versions 0.2.0 to 2.7.4, Granian aborts a worker process if a WSGI application returns an invalid HTTP response header name or value.

An issue was discovered in versions 6.0 before 6.0.5 and 5.2 before 5.2.14 regarding response headers that do not vary on cookies if a session is not modified, while `SESSION_SAVE_EVERY_REQUEST` is set to `True`. A remote attacker can steal a user's session after that user visits a cached public page.

An issue was discovered in versions 6.0 before 6.0.5 and 5.2 before 5.2.14 in `django.middleware.cache.UpdateCacheMiddleware`, which erroneously caches requests where the `Vary` header contained an asterisk (`'*'`). This can lead to private data being stored and served.

`NestedSecretsSettingsSource` reads secret values from files in a configured `secrets_dir`. When `secrets_nested_subdir=True`, a directory entry inside `secrets_dir` that is a symbolic link pointing outside `secrets_dir` is followed, allowing access to files outside the configured directory.
