CVE-2023-46049 2024-11-21 N/A 5.3 MEDIUM
LLVM 15.0.0 has a NULL pointer dereference in the parseOneMetadata() function via a crafted pdflatex.fmt file (or perhaps a crafted .o file) to llvm-lto. NOTE: this is disputed because the relationship between pdflatex.fmt and any LLVM language front end is not explained, and because a crash of the llvm-lto application should be categorized as a usability problem.
CVE-2023-46048 2024-11-21 N/A 6.2 MEDIUM
Tex Live 944e257 has a NULL pointer dereference in texk/web2c/pdftexdir/writet1.c. NOTE: this is disputed because it should be categorized as a usability problem.
CVE-2023-46046 2024-11-21 N/A 5.5 MEDIUM
An issue in MiniZinc before 2.8.0 allows a NULL pointer dereference via ti_expr in a crafted .mzn file. NOTE: this is disputed because there is no common libminizinc use case in which an unattended process is supposed to run forever to process a series of atttacker-controlled .mzn files.
CVE-2023-45935 2024-11-21 N/A 4.2 MEDIUM
Qt 6 through 6.6 was discovered to contain a NULL pointer dereference via the function QXcbConnection::initializeAllAtoms(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.
CVE-2023-45925 2024-11-21 N/A N/A
GNU Midnight Commander 4.8.29-146-g299d9a2fb was discovered to contain a NULL pointer dereference via the function x_error_handler() at tty/x11conn.c. NOTE: this is disputed because it should be categorized as a usability problem (an X operation silently fails).
CVE-2023-45924 2024-11-21 N/A 9.8 CRITICAL
libglxproto.c in OpenGL libglvnd bb06db5a was discovered to contain a segmentation violation via the function glXGetDrawableScreen(). NOTE: this is disputed because there are no common situations in which users require uninterrupted operation with an attacker-controller server.
CVE-2023-45680 1 Nothings 1 Stb Vorbis.c 2024-11-21 N/A 5.3 MEDIUM
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, the `f->comment_list` is set to `NULL`, but `f->comment_list_length` is not reset. Later in `vorbis_deinit` it tries to dereference the `NULL` pointer. This issue may lead to denial of service.
CVE-2023-45667 1 Nothings 1 Stb Image.h 2024-11-21 N/A 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-2023-42754 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-11-21 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.
CVE-2023-41909 3 Debian, Fedoraproject, Frrouting 3 Debian Linux, Fedora, Frrouting 2024-11-21 N/A 7.5 HIGH
An issue was discovered in FRRouting FRR through 9.0. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference.
CVE-2023-41633 1 Catdoc Project 1 Catdoc 2024-11-21 N/A 5.5 MEDIUM
Catdoc v0.95 was discovered to contain a NULL pointer dereference via the component xls2csv at src/fileutil.c.
CVE-2023-41358 3 Debian, Fedoraproject, Frrouting 3 Debian Linux, Fedora, Frrouting 2024-11-21 N/A 7.5 HIGH
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero.
CVE-2023-41274 1 Qnap 3 Qts, Quts Hero, Qutscloud 2024-11-21 N/A 5.5 MEDIUM
A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow authenticated administrators to launch a denial-of-service (DoS) attack via a network. We have already fixed the vulnerability in the following versions: QTS 5.1.2.2533 build 20230926 and later QuTS hero h5.1.2.2534 build 20230927 and later QuTScloud c5.1.5.2651 and later
CVE-2023-40546 2 Fedoraproject, Redhat 3 Fedora, Enterprise Linux, Shim 2024-11-21 N/A 6.2 MEDIUM
A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances.
CVE-2023-40459 1 Sierrawireless 8 Aleos, Es450, Gx450 and 5 more 2024-11-21 N/A 7.5 HIGH
The ACEManager component of ALEOS 4.16 and earlier does not adequately perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.
CVE-2023-40360 1 Qemu 1 Qemu 2024-11-21 N/A 5.5 MEDIUM
QEMU through 8.0.4 accesses a NULL pointer in nvme_directive_receive in hw/nvme/ctrl.c because there is no check for whether an endurance group is configured before checking whether Flexible Data Placement is enabled.
CVE-2023-3772 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.
CVE-2023-3603 1 Libssh 1 Libssh 2024-11-21 N/A 3.1 LOW
A missing allocation check in sftp server processing read requests may cause a NULL dereference on low-memory conditions. The malicious client can request up to 4GB SFTP reads, causing allocation of up to 4GB buffers, which was not being checked for failure. This will likely crash the authenticated user's sftp server connection (if implemented as forking as recommended). For thread-based servers, this might also cause DoS for legitimate users. Given this code is not in any released versions, no security releases have been issued.
CVE-2023-3355 1 Linux 1 Linux Kernel 2024-11-21 N/A 4.7 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's drivers/gpu/drm/msm/msm_gem_submit.c code in the submit_lookup_cmds function, which fails because it lacks a check of the return value of kmalloc(). This issue allows a local user to crash the system.
CVE-2023-3354 3 Fedoraproject, Qemu, Redhat 4 Fedora, Qemu, Enterprise Linux and 1 more 2024-11-21 N/A 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.
