CVE-2023-49083 2 Cryptography.io, Redhat 5 Cryptography, Ansible Automation Platform, Enterprise Linux and 2 more 2025-02-13 5.9 Medium
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability. This vulnerability has been patched in version 41.0.6.
CVE-2023-40032 1 Libvips 1 Libvips 2025-02-13 5.5 Medium
libvips is a demand-driven, horizontally threaded image processing library. A specially crafted SVG input can cause libvips versions 8.14.3 or earlier to segfault when attempting to parse a malformed UTF-8 character. Users should upgrade to libvips version 8.14.4 (or later) when processing untrusted input.
CVE-2023-3316 2 Libtiff, Redhat 2 Libtiff, Enterprise Linux 2025-02-13 5.9 Medium
A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones.
CVE-2023-28625 2 Openidc, Redhat 2 Mod Auth Openidc, Enterprise Linux 2025-02-13 7.5 High
mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using `OIDCStripCookies`.
CVE-2023-0401 3 Openssl, Redhat, Stormshield 4 Openssl, Enterprise Linux, Rhel Eus and 1 more 2025-02-13 7.5 High
A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider. PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS implementation in OpenSSL does not call these functions however third party applications would be affected if they call these functions to verify signatures on untrusted data.
CVE-2023-0217 2 Openssl, Redhat 3 Openssl, Enterprise Linux, Rhel Eus 2025-02-13 7.5 High
An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allow an attacker to cause a denial of service attack. The TLS implementation in OpenSSL does not call this function but applications might call the function if there are additional security requirements imposed by standards such as FIPS 140-3.
CVE-2023-0216 3 Openssl, Redhat, Stormshield 4 Openssl, Enterprise Linux, Rhel Eus and 1 more 2025-02-13 7.5 High
An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.
CVE-2021-33630 2 Huawei, Redhat 2 Openeuler, Enterprise Linux 2025-02-13 5.5 Medium
NULL Pointer Dereference vulnerability in openEuler kernel on Linux (network modules) allows Pointer Manipulation. This vulnerability is associated with program files net/sched/sch_cbs.C. This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3.
CVE-2023-46728 2 Redhat, Squid-cache 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2025-02-13 7.5 High
Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a NULL pointer dereference bug Squid is vulnerable to a Denial of Service attack against Squid's Gopher gateway. The gopher protocol is always available and enabled in Squid prior to Squid 6.0.1. Responses triggering this bug are possible to be received from any gopher server, even those without malicious intent. Gopher support has been removed in Squid version 6.0.1. Users are advised to upgrade. Users unable to upgrade should reject all gopher URL requests.
CVE-2023-45667 1 Nothings 2 Stb Image, Stb Image.h 2025-02-13 5.3 Medium
stb_image is a single file MIT licensed library for processing images. If `stbi__load_gif_main` in `stbi_load_gif_from_memory` fails it returns a null pointer and may keep the `z` variable uninitialized. In case the caller also sets the flip vertically flag, it continues and calls `stbi__vertical_flip_slices` with the null pointer result value and the uninitialized `z` value. This may result in a program crash.
CVE-2023-39351 4 Debian, Fedoraproject, Freerdp and 1 more 4 Debian Linux, Fedora, Freerdp and 1 more 2025-02-13 5.3 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX (rfx) handling. Inside the `rfx_process_message_tileset` function, the program allocates tiles using `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would cause a program crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-3354 3 Fedoraproject, Qemu, Redhat 10 Fedora, Qemu, Advanced Virtualization and 7 more 2025-02-13 7.5 High
A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
CVE-2023-26463 1 Strongswan 1 Strongswan 2025-02-13 9.8 Critical
strongSwan 5.9.8 and 5.9.9 potentially allows remote code execution because it uses a variable named "public" for two different purposes within the same function. There is initially incorrect access control, later followed by an expired pointer dereference. One attack vector is sending an untrusted client certificate during EAP-TLS. A server is affected only if it loads plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS, EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10.
CVE-2023-0779 1 Zephyrproject 1 Zephyr 2025-02-13 6.7 Medium
At the most basic level, an invalid pointer can be input that crashes the device, but with more knowledge of the device’s memory layout, further exploitation is possible.
CVE-2023-0458 3 Debian, Linux, Redhat 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more 2025-02-13 5.3 Medium
A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11
