kernel: race condition in vivid_stop_generating_vid_cap(),vivid_stop_generating_vid_out(), sdr_cap_stop_streaming()

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

kernel: The flow_dissector feature allows device tracking

The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

file: heap-based buffer overflow in cdf_read_property_info in cdf.c

cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).

OnCommand System Manager versions 9.3 prior to 9.3P18 and 9.4 prior to 9.4P2 are susceptible to a cross site scripting vulnerability that could allow an authenticated attacker to inject arbitrary scripts into the SNMP Community Names label field.

OnCommand Cloud Manager versions prior to 3.8.0 are susceptible to arbitrary code execution by remote attackers.

NetApp FAS 8300/8700 and AFF A400 Baseboard Management Controller (BMC) firmware versions 13.x prior to 13.1P1 were shipped with a default account enabled that could allow unauthorized arbitrary command execution via local access.

E-Series SANtricity OS Controller Software version 11.60.0 is susceptible to a vulnerability which allows an attacker to cause a Denial of Service (DoS) in IPv6 environments.

All versions of ONTAP Select Deploy administration utility are susceptible to a vulnerability which when successfully exploited could allow an administrative user to escalate their privileges.

PuTTY before 0.73 might allow remote SSH-1 servers to cause a denial of service by accessing freed memory locations via an SSH1_MSG_DISCONNECT message.

nss: Check length of inputs for cryptographic primitives

In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length checks. In cases where the application calling the library did not perform a sanity check on the inputs it could result in a crash due to a buffer overflow.

kernel: Memory leak in hsr_dev_finalize() in net/hsr/hsr_device.c

In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.

golang: HTTP/1.1 headers with a space before the colon leads to filter bypass or request smuggling

Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.

kernel: backporting error in ptrace_get_debugreg()

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream "x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped.

In FreeBSD 12.1-STABLE before r356035, 12.1-RELEASE before 12.1-RELEASE-p4, 11.3-STABLE before r356036, and 11.3-RELEASE before 11.3-RELEASE-p8, incomplete packet data validation may result in memory access after it has been freed leading to a kernel panic or other unpredictable results.

kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c

An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.

kernel: Null pointer dereference in the sound/usb/line6/driver.c

An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/driver.c driver.

kernel: Null pointer dereference in the sound/usb/helper.c

An issue was discovered in the Linux kernel before 5.2.8. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/helper.c (motu_microbookii) driver.

kernel: Null pointer dereference in the sound/usb/line6/pcm.c

An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/pcm.c driver.

kernel: Use-after-free in drivers/net/wireless/intersil/p54/p54usb.c

An issue was discovered in the Linux kernel before 5.2.1. There is a use-after-free caused by a malicious USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver.

kernel: null-pointer dereference in drivers/usb/misc/yurex.c driver

An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver.
