CVE-2019-14283 1 Linux 1 Linux Kernel 2024-11-21 4.6 MEDIUM 6.8 MEDIUM
In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default.
CVE-2019-13648 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c.
CVE-2019-13631 1 Linux 1 Linux Kernel 2024-11-21 4.6 MEDIUM 6.8 MEDIUM
In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages.
CVE-2019-13456 4 Freeradius, Linux, Opensuse and 1 more 4 Freeradius, Linux Kernel, Leap and 1 more 2024-11-21 2.9 LOW 6.5 MEDIUM
In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user. This information leakage is similar to the "Dragonblood" attack and CVE-2019-9494.
CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2024-11-21 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2019-13233 1 Linux 1 Linux Kernel 2024-11-21 4.4 MEDIUM 7.0 HIGH
In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds violation.
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-2019-12881 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-2019-12819 1 Linux 1 Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service.
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-2019-12817 6 Canonical, Debian, Fedoraproject and 3 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
arch/powerpc/mm/mmu_context_book3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected.
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-2019-12579 3 Apple, Linux, Londontrustmedia 3 Macos, Linux Kernel, Private Internet Access Vpn Client 2024-11-21 7.2 HIGH 7.8 HIGH
A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The PIA Linux/macOS binary openvpn_launcher.64 binary is setuid root. This binary accepts several parameters to update the system configuration. These parameters are passed to operating system commands using a "here" document. The parameters are not sanitized, which allow for arbitrary commands to be injected using shell metacharacters. A local unprivileged user can pass special crafted parameters that will be interpolated by the operating system calls.
CVE-2019-12578 2 Linux, Londontrustmedia 2 Linux Kernel, Private Internet Access Vpn Client 2024-11-21 7.2 HIGH 7.8 HIGH
A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The openvpn_launcher.64 binary is setuid root. This binary executes /opt/pia/openvpn-64/openvpn, passing the parameters provided from the command line. Care was taken to programmatically disable potentially dangerous openvpn parameters; however, the --route-pre-down parameter can be used. This parameter accepts an arbitrary path to a script/program to be executed when OpenVPN exits. The --script-security parameter also needs to be passed to allow for this action to be taken, and --script-security is not currently in the disabled parameter list. A local unprivileged user can pass a malicious script/binary to the --route-pre-down option, which will be executed as root when openvpn is stopped.
CVE-2019-12575 2 Linux, Londontrustmedia 2 Linux Kernel, Private Internet Access Vpn Client 2024-11-21 7.2 HIGH 7.8 HIGH
A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The root_runner.64 binary is setuid root. This binary executes /opt/pia/ruby/64/ruby, which in turn attempts to load several libraries under /tmp/ruby-deploy.old/lib. A local unprivileged user can create a malicious library under this path to execute arbitrary code as the root user.
CVE-2019-12573 3 Apple, Linux, Londontrustmedia 3 Macos, Linux Kernel, Private Internet Access Vpn Client 2024-11-21 6.6 MEDIUM 7.1 HIGH
A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated, local attacker to overwrite arbitrary files. The openvpn_launcher binary is setuid root. This binary supports the --log option, which accepts a path as an argument. This parameter is not sanitized, which allows a local unprivileged user to overwrite arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.
CVE-2019-12456 1 Linux 1 Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used
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-2019-12454 1 Linux 1 Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
An issue was discovered in wcd9335_codec_enable_dec in sound/soc/codecs/wcd9335.c in the Linux kernel through 5.1.5. It uses kstrndup instead of kmemdup_nul, which allows attackers to have an unspecified impact via unknown vectors. NOTE: The vendor disputes this issues as not being a vulnerability because switching to kmemdup_nul() would only fix a security issue if the source string wasn't NUL-terminated, which is not the case
