kernel: TOCTOU mismatch in the NFS client code

A flaw was found in the NFSv4 implementation where when mounting a remote attacker controlled server it could return specially crafted response allow for local memory corruption and possibly privilege escalation...

kernel: NFS client crash due to index buffer overflow during Direct IO write causing kernel panic

A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause a kernel panic. The highest threat from this vulnerability is to data confidentiality...

A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c aka CID-b4487b935452.

Linux kernel information disclosure vulnerability (CNVD-2020-51796)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An information disclosure vulnerability exists in Linux kernel before version 5.8.3, which stems from a TOCTOU mismatch in the NFS client code. An attacker can exploit...

UBUNTU-CVE-2020-25212

A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452...

CVE-2020-24394

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c in the NFS server can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered...

kernel: nfs: use-after-free in svc_process_common()

A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bcsvcprocess use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and ...

USN-4400-1 nfs-utils vulnerability

It was discovered that the nfs-utils package set incorrect permissions on the /var/lib/nfs directory. An attacker could possibly use this issue to escalate privileges...

CVE-2020-3263 Cisco Webex Meetings Desktop App URL Filtering Arbitrary Program Execution Vulnerability

A vulnerability in Cisco Webex Meetings Desktop App could allow an unauthenticated, remote attacker to execute programs on an affected end-user system. The vulnerability is due to improper validation of input that is supplied to application URLs. The attacker could exploit this vulnerability by...

Design/Logic Flaw

The file transfer component of TIBCO Software Inc.'s TIBCO Managed File Transfer Platform Server for IBM i contains a vulnerability that theoretically allows an attacker to perform unauthorized network file transfers to and from the file system accessible to the affected component. This...

Pengutronix barebox buffer overflow vulnerability (CNVD-2020-36741)

Pengutronix barebox is a bootloader used in embedded Linux systems. A buffer overflow vulnerability exists in the nfsreadreply file in net/nfs.c in Pengutronix barebox version 2020.05.0 and earlier. The vulnerability originates when a network system or product performs an operation in memory...

Wireshark Resource Management Error Vulnerability

Wireshark formerly known as Ethereal is a suite of network packet analysis software from the Wireshark team. The function of the software is to intercept network packets and display detailed data for analysis. A security vulnerability exists in Wireshark versions 3.2.0 through 3.2.3, 3.0.0 throug...

DEBIAN-CVE-2020-13164

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem...

kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence

A flaw was found in the Linux kernel's NFS implementation. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the...
