CVE-2020-27830 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 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 4.3 MEDIUM 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 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 6.8 MEDIUM 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-2020-27279 1 Redlion 1 Crimson 2024-11-21 7.8 HIGH 7.5 HIGH
A NULL pointer deference vulnerability has been identified in the protocol converter. An attacker could send a specially crafted packet that could reboot the device running Crimson 3.1 (Build versions prior to 3119.001).
CVE-2020-27277 1 Deltaww 1 Dopsoft 2024-11-21 9.3 HIGH 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-2020-26536 1 Foxitsoftware 2 Foxit Reader, Phantompdf 2024-11-21 4.3 MEDIUM 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 5.0 MEDIUM 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-2020-26235 2 Microsoft, Time Project 2 Windows, Time 2024-11-21 3.5 LOW 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 5.0 MEDIUM 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 5.0 MEDIUM 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 5.0 MEDIUM 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 5.0 MEDIUM 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 2.1 LOW 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 2.1 LOW 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 2.1 LOW 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 5 Cloud Backup, Solidfire Baseboard Management Controller, Solidfire Baseboard Management Controller Firmware and 2 more 2024-11-21 5.0 MEDIUM 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.
CVE-2020-25639 3 Fedoraproject, Linux, Redhat 5 Fedora, Linux Kernel, Enterprise Linux and 2 more 2024-11-21 4.9 MEDIUM 4.4 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system.
CVE-2020-25467 2 Debian, Long Range Zip Project 2 Debian Linux, Long Range Zip 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A null pointer dereference was discovered lzo_decompress_buf in stream.c in Irzip 0.621 which allows an attacker to cause a denial of service (DOS) via a crafted compressed file.
