CVE-2020-27830 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 5.5 Medium
A vulnerability was found in Linux Kernel where in the spk_ttyio_receive_buf2() function, it would dereference spk_ttyio_synth without checking whether it is NULL or not, and may lead to a NULL-ptr deref crash.
CVE-2020-27819 1 Libxls Project 1 Libxls 2024-11-21 5.5 Medium
An issue was discovered in libxls before and including 1.6.1 when reading Microsoft Excel files. A NULL pointer dereference vulnerability exists when parsing XLS cells in libxls/xls2csv.c:199. It could allow a remote attacker to cause a denial of service via crafted XLS file.
CVE-2020-27675 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.7 Medium
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.
CVE-2020-27289 1 Deltaww 1 Cncsoft-b 2024-11-21 7.8 High
Delta Electronics CNCSoft-B Versions 1.0.0.2 and prior has a null pointer dereference issue while processing project files, which may allow an attacker to execute arbitrary code.
CVE-2020-27277 1 Deltaww 1 Dopsoft 2024-11-21 7.8 High
Delta Electronics DOPSoft Version 4.0.8.21 and prior has a null pointer dereference issue while processing project files, which may allow an attacker to execute arbitrary code.
CVE-2020-26991 1 Siemens 2 Jt2go, Teamcenter Visualization 2024-11-21 8.8 High
A vulnerability has been identified in JT2Go (All versions < V13.1.0.2), Teamcenter Visualization (All versions < V13.1.0.2). Affected applications lack proper validation of user-supplied data when parsing ASM files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11899)
CVE-2020-26536 1 Foxitsoftware 2 Foxit Reader, Phantompdf 2024-11-21 5.5 Medium
An issue was discovered in Foxit Reader and PhantomPDF before 10.1. There is a NULL pointer dereference via a crafted PDF document.
CVE-2020-26521 2 Fedoraproject, Linuxfoundation 2 Fedora, Nats-server 2024-11-21 7.5 High
The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code).
CVE-2020-26268 1 Google 1 Tensorflow 2024-11-21 4.4 Medium
In affected versions of TensorFlow the tf.raw_ops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area. If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault. This is because the allocator used to return the buffer data is not marked as returning an opaque handle since the needed virtual method is not overridden. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.
CVE-2020-26245 1 Systeminformation 1 Systeminformation 2024-11-21 8.1 High
npm package systeminformation before version 4.30.5 is vulnerable to Prototype Pollution leading to Command Injection. The issue was fixed with a rewrite of shell sanitations to avoid prototyper pollution problems. The issue is fixed in version 4.30.5. If you cannot upgrade, be sure to check or sanitize service parameter strings that are passed to si.inetChecksite().
CVE-2020-26237 4 Debian, Highlightjs, Oracle and 1 more 4 Debian Linux, Highlight.js, Mysql Enterprise Monitor and 1 more 2024-11-21 5.8 Medium
Highlight.js is a syntax highlighter written in JavaScript. Highlight.js versions before 9.18.2 and 10.1.2 are vulnerable to Prototype Pollution. A malicious HTML code block can be crafted that will result in prototype pollution of the base object's prototype during highlighting. If you allow users to insert custom HTML code blocks into your page/app via parsing Markdown code blocks (or similar) and do not filter the language names the user can provide you may be vulnerable. The pollution should just be harmless data but this can cause problems for applications not expecting these properties to exist and can result in strange behavior or application crashes, i.e. a potential DOS vector. If your website or application does not render user provided data it should be unaffected. Versions 9.18.2 and 10.1.2 and newer include fixes for this vulnerability. If you are using version 7 or 8 you are encouraged to upgrade to a newer release.
CVE-2020-26235 2 Microsoft, Time Project 2 Windows, Time 2024-11-21 5.3 Medium
In Rust time crate from version 0.2.7 and before version 0.2.23, unix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires the user to set any environment variable in a different thread than the affected functions. The affected functions are time::UtcOffset::local_offset_at, time::UtcOffset::try_local_offset_at, time::UtcOffset::current_local_offset, time::UtcOffset::try_current_local_offset, time::OffsetDateTime::now_local and time::OffsetDateTime::try_now_local. Non-Unix targets are unaffected. This includes Windows and wasm. The issue was introduced in version 0.2.7 and fixed in version 0.2.23.
CVE-2020-26213 1 Teler Project 1 Teler 2024-11-21 5.9 Medium
In teler before version 0.0.1, if you run teler inside a Docker container and encounter `errors.Exit` function, it will cause denial-of-service (`SIGSEGV`) because it doesn't get process ID and process group ID of teler properly to kills. The issue is patched in teler 0.0.1 and 0.0.1-dev5.1.
CVE-2020-25866 4 Fedoraproject, Opensuse, Oracle and 1 more 4 Fedora, Leap, Zfs Storage Appliance Kit and 1 more 2024-11-21 7.5 High
In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs.
CVE-2020-25858 1 Qualcomm 1 Qualcomm Mobile Access Point 2024-11-21 7.5 High
The QCMAP_Web_CLIENT binary in the Qualcomm QCMAP software suite prior to versions released in October 2020 does not validate the return value of a strstr() or strchr() call in the Tokenizer() function. An attacker who invokes the web interface with a crafted URL can crash the process, causing denial of service. This version of QCMAP is used in many kinds of networking devices, primarily mobile hotspots and LTE routers.
CVE-2020-25821 1 Peg-markdown Project 1 Peg-markdown 2024-11-21 7.5 High
peg-markdown 0.4.14 has a NULL pointer dereference in process_raw_blocks in markdown_lib.c. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
CVE-2020-25743 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack Platform 2024-11-21 3.2 Low
hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call.
CVE-2020-25742 1 Qemu 1 Qemu 2024-11-21 3.2 Low
pci_change_irq_level in hw/pci/pci.c in QEMU before 5.1.1 has a NULL pointer dereference because pci_get_bus() might not return a valid pointer.
CVE-2020-25741 1 Qemu 1 Qemu 2024-11-21 3.2 Low
fdctrl_write_data in hw/block/fdc.c in QEMU 5.0.0 has a NULL pointer dereference via a NULL block pointer for the current drive.
CVE-2020-25692 3 Netapp, Openldap, Redhat 6 Cloud Backup, Solidfire Baseboard Management Controller, Solidfire Baseboard Management Controller Firmware and 3 more 2024-11-21 7.5 High
A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service.
