A Denial-of-Service (DoS) vulnerability was discovered in F-Secure Linux Security whereby the FSAVD component used in certain F-Secure products can crash while scanning larger packages/fuzzed files. The exploit can be triggered remotely by an attacker. A successful attack will result in Denial-of-Service (DoS) of the Anti-Virus engine.
CVE-2017-18189 2 Debian, Sound Exchange Project 2 Debian Linux, Sound Exchange 2021-06-24 5.0 MEDIUM 7.5 HIGH
In the startread function in xa.c in Sound eXchange (SoX) through 14.4.2, a corrupt header specifying zero channels triggers an infinite loop with a resultant NULL pointer dereference, which may allow a remote attacker to cause a denial-of-service.
CVE-2021-0555 1 Google 1 Android 2021-06-24 5.0 MEDIUM 7.5 HIGH
In RenderStruct of protostream_objectsource.cc, there is a possible crash due to a missing null check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-179161711
CVE-2014-0190 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Opensuse and 1 more 2021-06-16 4.3 MEDIUM N/A
The GIF decoder in QtGui in Qt before 5.3 allows remote attackers to cause a denial of service (NULL pointer dereference) via invalid width and height values in a GIF image.
CVE-2020-13435 2 Fedoraproject, Sqlite 2 Fedora, Sqlite 2021-06-14 2.1 LOW 5.5 MEDIUM
SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.
CVE-2019-18885 1 Linux 1 Linux Kernel 2021-06-14 2.1 LOW 5.5 MEDIUM
fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15.
CVE-2018-14613 1 Linux 1 Linux Kernel 2021-06-14 7.1 HIGH 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c.
CVE-2019-14584 1 Tianocore 1 Edk2 2021-06-11 4.6 MEDIUM 7.8 HIGH
Null pointer dereference in Tianocore EDK2 may allow an authenticated user to potentially enable escalation of privilege via local access.
CVE-2019-17539 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2021-06-10 7.5 HIGH 9.8 CRITICAL
In FFmpeg before 4.2, avcodec_open2 in libavcodec/utils.c allows a NULL pointer dereference and possibly unspecified other impact when there is no valid close function pointer.
CVE-2021-30500 3 Fedoraproject, Redhat, Upx Project 3 Fedora, Enterprise Linux, Upx 2021-06-07 6.8 MEDIUM 7.8 HIGH
Null pointer dereference was found in upx PackLinuxElf::canUnpack() in p_lx_elf.cpp,in version UPX 4.0.0. That allow attackers to execute arbitrary code and cause a denial of service via a crafted file.
CVE-2017-3169 1 Apache 1 Http Server 2021-06-06 7.5 HIGH 9.8 CRITICAL
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
CVE-2018-8011 2 Apache, Netapp 2 Http Server, Cloud Backup 2021-06-06 5.0 MEDIUM 7.5 HIGH
By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33).
CVE-2018-1302 3 Apache, Canonical, Netapp 6 Http Server, Ubuntu Linux, Clustered Data Ontap and 3 more 2021-06-06 4.3 MEDIUM 5.9 MEDIUM
When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.
CVE-2017-7659 1 Apache 1 Http Server 2021-06-06 5.0 MEDIUM 7.5 HIGH
A maliciously constructed HTTP/2 request could cause mod_http2 in Apache HTTP Server 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process.
CVE-2021-30178 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2021-06-04 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 5.11.11. synic_get in arch/x86/kvm/hyperv.c has a NULL pointer dereference for certain accesses to the SynIC Hyper-V context, aka CID-919f4ebc5987.
CVE-2021-3514 1 Redhat 1 389 Directory Server 2021-06-04 4.0 MEDIUM 6.5 MEDIUM
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
CVE-2019-12615 2 Linux, Netapp 10 Linux Kernel, Active Iq Unified Manager, Aff A700s and 7 more 2021-06-02 7.8 HIGH 7.5 HIGH
An issue was discovered in get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup_const of node_info->vdev_port.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
CVE-2020-18395 1 Gnu 1 Gama 2021-06-01 5.0 MEDIUM 7.5 HIGH
A NULL-pointer deference issue was discovered in GNU_gama::set() in ellipsoid.h in Gama 2.04 which can lead to a denial of service (DOS) via segment faults caused by crafted inputs.
