| Observable behavioral in power management throttling for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via network access. |
| In the Linux kernel, the following vulnerability has been resolved:
net: amd-xgbe: Fix skb data length underflow
There will be BUG_ON() triggered in include/linux/skbuff.h leading to
intermittent kernel panic, when the skb length underflow is detected.
Fix this by dropping the packet if such length underflows are seen
because of inconsistencies in the hardware descriptors. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Disable coherent dumb buffers without 3d
Coherent surfaces make only sense if the host renders to them using
accelerated apis. Without 3d the entire content of dumb buffers stays
in the guest making all of the extra work they're doing to synchronize
between guest and host useless.
Configurations without 3d also tend to run with very low graphics
memory limits. The pinned console fb, mob cursors and graphical login
manager tend to run out of 16MB graphics memory that those guests use.
Fix it by making sure the coherent dumb buffers are only used on
configs with 3d enabled. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()
Syzbot reported a hang issue in migrate_pages_batch() called by mbind()
and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2.
While migrate_pages_batch() locks a folio and waits for the writeback to
complete, the log writer thread that should bring the writeback to
completion picks up the folio being written back in
nilfs_lookup_dirty_data_buffers() that it calls for subsequent log
creation and was trying to lock the folio. Thus causing a deadlock.
In the first place, it is unexpected that folios/pages in the middle of
writeback will be updated and become dirty. Nilfs2 adds a checksum to
verify the validity of the log being written and uses it for recovery at
mount, so data changes during writeback are suppressed. Since this is
broken, an unclean shutdown could potentially cause recovery to fail.
Investigation revealed that the root cause is that the wait for writeback
completion in nilfs_page_mkwrite() is conditional, and if the backing
device does not require stable writes, data may be modified without
waiting.
Fix these issues by making nilfs_page_mkwrite() wait for writeback to
finish regardless of the stable write requirement of the backing device. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix underflow in second superblock position calculations
Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second
superblock, underflows when the argument device size is less than 4096
bytes. Therefore, when using this macro, it is necessary to check in
advance that the device size is not less than a lower limit, or at least
that underflow does not occur.
The current nilfs2 implementation lacks this check, causing out-of-bound
block access when mounting devices smaller than 4096 bytes:
I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0
phys_seg 1 prio class 2
NILFS (loop0): unable to read secondary superblock (blocksize = 1024)
In addition, when trying to resize the filesystem to a size below 4096
bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number
of segments to nilfs_sufile_resize(), corrupting parameters such as the
number of segments in superblocks. This causes excessive loop iterations
in nilfs_sufile_resize() during a subsequent resize ioctl, causing
semaphore ns_segctor_sem to block for a long time and hang the writer
thread:

This fixes these issues by inserting appropriate minimum device size
checks or anti-underflow checks, depending on where the macro is used. |
| Ember ZNet between v7.2.0 and v7.4.0 used software AES-CCM instead of integrated hardware cryptographic accelerators, potentially increasing risk of electromagnetic and differential power analysis sidechannel attacks. |
| An issue was discovered on the D-Link DWR-932B router. WPS PIN generation is based on srand(time(0)) seeding. |
| A buffer underflow vulnerability exists in the way Hword of Hancom Office 2020 version 11.0.0.5357 parses XML-based office files. A specially-crafted malformed file can cause memory corruption by using memory before buffer start, which can lead to code execution. A victim would need to access a malicious file to trigger this vulnerability. |
| Post-Quantum Secure Feldman's Verifiable Secret Sharing provides a Python implementation of Feldman's Verifiable Secret Sharing (VSS) scheme. In versions 0.8.0b2 and prior, the `secure_redundant_execution` function in feldman_vss.py attempts to mitigate fault injection attacks by executing a function multiple times and comparing results. However, several critical weaknesses exist. Python's execution environment cannot guarantee true isolation between redundant executions, the constant-time comparison implementation in Python is subject to timing variations, the randomized execution order and timing provide insufficient protection against sophisticated fault attacks, and the error handling may leak timing information about partial execution results. These limitations make the protection ineffective against targeted fault injection attacks, especially from attackers with physical access to the hardware. A successful fault injection attack could allow an attacker to bypass the redundancy check mechanisms, extract secret polynomial coefficients during share generation or verification, force the acceptance of invalid shares during verification, and/or manipulate the commitment verification process to accept fraudulent commitments. This undermines the core security guarantees of the Verifiable Secret Sharing scheme. As of time of publication, no patched versions of Post-Quantum Secure Feldman's Verifiable Secret Sharing exist, but other mitigations are available. Long-term remediation requires reimplementing the security-critical functions in a lower-level language like Rust. Short-term mitigations include deploying the software in environments with physical security controls, increasing the redundancy count (from 5 to a higher number) by modifying the source code, adding external verification of cryptographic operations when possible, considering using hardware security modules (HSMs) for key operations. |
| NVIDIA Hopper HGX for 8-GPU contains a vulnerability in the HGX Management Controller (HMC) that may allow a malicious actor with administrative access on the BMC to access the HMC as an administrator. A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. |
| Inclusion of undocumented features issue exists in UD-LT2 firmware Ver.1.00.008_SE and earlier. A remote attacker may disable the LAN-side firewall function of the affected products, and open specific ports. |
| Dell PowerProtect DD, versions prior to DDOS 8.3.0.0, 7.10.1.50, and 7.13.1.10 contains a use of a Cryptographic Primitive with a Risky Implementation vulnerability. A remote attacker could potentially exploit this vulnerability, leading to Information tampering. |
| Dell Key Trust Platform, v3.0.6 and prior, contains Use of a Cryptographic Primitive with a Risky Implementation vulnerability. A local privileged attacker could potentially exploit this vulnerability, leading to privileged information disclosure. |
| Plonky2 is a SNARK implementation based on techniques from PLONK and FRI. Lookup tables, whose length is not divisible by 26 = floor(num_routed_wires / 3) always include the 0 -> 0 input-output pair. Thus a malicious prover can always prove that f(0) = 0 for any lookup table f (unless its length happens to be divisible by 26). The cause of problem is that the LookupTableGate-s are padded with zeros. A workaround from the user side is to extend the table (by repeating some entries) so that its length becomes divisible by 26. This vulnerability is fixed in 1.0.1. |
| Inclusion of undocumented features or chicken bits issue exists in UD-LT1 firmware Ver.2.1.8 and earlier and UD-LT1/EX firmware Ver.2.1.8 and earlier. A remote attacker may disable the firewall function of the affected products. As a result, an arbitrary OS command may be executed and/or configuration settings of the device may be altered. |
| There is a buffer error vulnerability in some Huawei product. An unauthenticated attacker may send special UPNP message to the affected products. Due to insufficient input validation of some value, successful exploit may cause some service abnormal. (Vulnerability ID: HWPSIRT-2017-08234)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2020-9086. |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It has been discovered that an unprivileged pod in a different namespace on the same cluster could connect to the Redis server on port 6379. Despite having installed the latest version of the VPC CNI plugin on the EKS cluster, it requires manual enablement through configuration to enforce network policies. This raises concerns that many clients might unknowingly have open access to their Redis servers. This vulnerability could lead to Privilege Escalation to the level of cluster controller, or to information leakage, affecting anyone who does not have strict access controls on their Redis instance. This issue has been patched in version(s) 2.8.19, 2.9.15 and 2.10.10. |
| Animate versions 23.0.8, 24.0.5 and earlier are affected by a Buffer Underwrite ('Buffer Underflow') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could leverage this vulnerability to manipulate memory in such a way that they could execute code under the privileges of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| Inclusion of undocumented features or chicken bits issue exists in AE1021 firmware versions 2.0.10 and earlier and AE1021PE firmware versions 2.0.10 and earlier, which may allow a logged-in user to enable telnet service. |
