CVE-2019-12984 1 Linux 1 Linux Kernel 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in net/nfc/netlink.c in the Linux kernel before 5.1.13 can be triggered by a malicious user-mode program that omits certain NFC attributes, leading to denial of service.
CVE-2019-12974 1 Imagemagick 1 Imagemagick 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference in the function ReadPANGOImage in coders/pango.c and the function ReadVIDImage in coders/vid.c in ImageMagick 7.0.8-34 allows remote attackers to cause a denial of service via a crafted image.
CVE-2019-12881 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 4.6 MEDIUM 7.8 HIGH
i915_gem_userptr_get_pages in drivers/gpu/drm/i915/i915_gem_userptr.c in the Linux kernel 4.15.0 on Ubuntu 18.04.2 allows local users to cause a denial of service (NULL pointer dereference and BUG) or possibly have unspecified other impact via crafted ioctl calls to /dev/dri/card0.
CVE-2019-12818 1 Linux 1 Linux Kernel 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c.
CVE-2019-12654 1 Cisco 17 1000 Integrated Services Router, 1100 Integrated Services Router, 4000 Integrated Services Router and 14 more 2024-11-21 7.8 HIGH 7.5 HIGH
A vulnerability in the common Session Initiation Protocol (SIP) library of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on an internal data structure. An attacker could exploit this vulnerability by sending a sequence of malicious SIP messages to an affected device. An exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the iosd process. This triggers a reload of the device.
CVE-2019-12647 1 Cisco 28 1100, 4221, 4321 and 25 more 2024-11-21 7.8 HIGH 7.5 HIGH
A vulnerability in the Ident protocol handler of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability exists because the affected software incorrectly handles memory structures, leading to a NULL pointer dereference. An attacker could exploit this vulnerability by opening a TCP connection to specific ports and sending traffic over that connection. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.
CVE-2019-12615 2 Linux, Netapp 10 Linux Kernel, Active Iq Unified Manager, Aff A700s and 7 more 2024-11-21 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-2019-12614 5 Canonical, Fedoraproject, Linux and 2 more 5 Ubuntu Linux, Fedora, Linux Kernel and 2 more 2024-11-21 4.7 MEDIUM 4.1 MEDIUM
An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
CVE-2019-12482 1 Gpac 1 Gpac 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GPAC 0.7.1. There is a NULL pointer dereference in the function gf_isom_get_original_format_type at isomedia/drm_sample.c in libgpac.a, as demonstrated by MP4Box.
CVE-2019-12481 1 Gpac 1 Gpac 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in GPAC 0.7.1. There is a NULL pointer dereference in the function GetESD at isomedia/track.c in libgpac.a, as demonstrated by MP4Box.
CVE-2019-12455 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in sunxi_divs_clk_setup in drivers/clk/sunxi/clk-sunxi.c in the Linux kernel through 5.1.5. There is an unchecked kstrndup of derived_name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: This id is disputed as not being an issue because “The memory allocation that was not checked is part of a code that only runs at boot time, before user processes are started. Therefore, there is no possibility for an unprivileged user to control it, and no denial of service.”
CVE-2019-12436 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Samba 4.10.x before 4.10.5 has a NULL pointer dereference, leading to an AD DC LDAP server Denial of Service. This is related to an attacker using the paged search control. The attacker must have directory read access in order to attempt an exploit.
CVE-2019-12435 1 Samba 1 Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
Samba 4.9.x before 4.9.9 and 4.10.x before 4.10.5 has a NULL pointer dereference, leading to Denial of Service. This is related to the AD DC DNS management server (dnsserver) RPC server process.
CVE-2019-12412 1 Apache 1 Libapreq2 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw in the libapreq2 v2.07 to v2.13 multipart parser can deference a null pointer leading to a process crash. A remote attacker could send a request causing a process crash which could lead to a denial of service attack.
CVE-2019-12382 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference
CVE-2019-12381 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL
CVE-2019-12378 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: This has been disputed as not an issue
CVE-2019-12312 1 Libreswan 1 Libreswan 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Libreswan 3.27 an assertion failure can lead to a pluto IKE daemon restart. An attacker can trigger a NULL pointer dereference by initiating an IKEv2 IKE_SA_INIT exchange, followed by a bogus INFORMATIONAL exchange instead of the normallly expected IKE_AUTH exchange. This affects send_v2N_spi_response_from_state() in programs/pluto/ikev2_send.c that will then trigger a NULL pointer dereference leading to a restart of libreswan.
CVE-2019-12259 4 Belden, Siemens, Sonicwall and 1 more 49 Garrettcom Magnum Dx940e, Garrettcom Magnum Dx940e Firmware, Hirschmann Dragon Mach4000 and 46 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Wind River VxWorks 6.6, 6.7, 6.8, 6.9 and vx7 has an array index error in the IGMPv3 client component. There is an IPNET security vulnerability: DoS via NULL dereference in IGMP parsing.
CVE-2019-12218 1 Libsdl 2 Sdl2 Image, Simple Directmedia Layer 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in libSDL2.a in Simple DirectMedia Layer (SDL) 2.0.9 when used in conjunction with libSDL2_image.a in SDL2_image 2.0.4. There is a NULL pointer dereference in the SDL2_image function IMG_LoadPCX_RW at IMG_pcx.c.
