kernel: double-free caused by malicious USB device in drivers/usb/misc/rio500.c

An issue was discovered in the Linux kernel before 5.1.8. There is a double-free caused by a malicious USB device in the drivers/usb/misc/rio500.c driver.

kernel: use-after-free in drivers/media/v4l2-core/v4l2-dev.c

An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/v4l2-core/v4l2-dev.c driver because drivers/media/radio/radio-raremono.c does not properly allocate memory.

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h.

In DjVuLibre 3.5.27, the sorting functionality (aka GArrayTemplate<TYPE>::sort) allows attackers to cause a denial-of-service (application crash due to an Uncontrolled Recursion) by crafting a PBM image file that is mishandled in libdjvu/GContainer.h.

In DjVuLibre 3.5.27, the bitmap reader component allows attackers to cause a denial-of-service error (resource exhaustion caused by a GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file, related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp.

In DjVuLibre 3.5.27, DjVmDir.cpp in the DJVU reader component allows attackers to cause a denial-of-service (application crash in GStringRep::strdup in libdjvu/GString.cpp caused by a heap-based buffer over-read) by crafting a DJVU file.

giflib: divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c

In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.

kernel: mishandling recursion in sound/usb/mixer.c leading to kernel stack exhaustion and crash

check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to kernel stack exhaustion.

kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash

drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via an incomplete address in an endpoint descriptor.

kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath6kl/usb.c leads to a crash

drivers/net/wireless/ath/ath6kl/usb.c in the Linux kernel through 5.2.9 has a NULL pointer dereference via an incomplete address in an endpoint descriptor.

kernel: An out-of-bounds read in drivers/scsi/qedi/qedi_dbg.c leading to crash or information disclosure

An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the Linux kernel before 5.1.12. In the qedi_dbg_* family of functions, there is an out-of-bounds read.

kernel: powerpc: local user can read vector registers of other users' processes via an interrupt

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.

kernel: powerpc: local user can read vector registers of other users' processes via a Facility Unavailable exception

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check.

ImageMagick: division by zero in MeanShiftImage in MagickCore/feature.c

In ImageMagick 7.x before 7.0.8-41 and 6.x before 6.9.10-41, there is a divide-by-zero vulnerability in the MeanShiftImage function. It allows an attacker to cause a denial of service by sending a crafted file.

samba: Replication of ACLs set to inherit down a subtree on AD Directory not automatic

There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would not automatically be taken away on all domain controllers.

kernel: heap overflow in marvell/mwifiex/tdls.c

A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.

kernel: stack-based buffer overflow in add_ie_rates function in drivers/net/wireless/marvell/libertas/cfg.c

A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.

kernel: heap-based buffer overflow in lbs_ibss_join_existing function in drivers/net/wireless/marvell/libertas/cfg.c

A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.

kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c

A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.

libssh: unsanitized location in scp could lead to unwanted command execution

A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.
