nfc: s3fwrn5: allocate rx skb before consuming bytes

In the Linux kernel, the following vulnerability has been resolved: nfc: s3fwrn5: allocate rx skb before consuming bytes s3fwrn82_uart_read() reports the number of accepted bytes to the serdev core. The current code consumes bytes into recv_skb and may already deliver a complete frame before allocating a fresh receive buffer. If that alloc_skb() fails, the callback returns 0 even though it has already consumed bytes, and it leaves recv_skb as NULL for the next receive callback. That breaks the receive_buf() accounting contract and can also lead to a NULL dereference on the next skb_put_u8(). Allocate the receive skb lazily before consuming the next byte instead. If allocation fails, return the number of bytes already accepted.

cpufreq: Avoid a bad reference count on CPU node

In the Linux kernel, the following vulnerability has been resolved: cpufreq: Avoid a bad reference count on CPU node In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute.

net/sched: act_ct: fix ref leak when switching zones

In the Linux kernel, the following vulnerability has been resolved: net/sched: act_ct: fix ref leak when switching zones When switching zones or network namespaces without doing a ct clear in between, it is now leaking a reference to the old ct entry. That's because tcf_ct_skb_nfct_cached() returns false and tcf_ct_flow_table_lookup() may simply overwrite it. The fix is to, as the ct entry is not reusable, free it already at tcf_ct_skb_nfct_cached().

Improper Access Control in Elfatek Elektronics' ANKA JPD-00028

Missing Critical Step in Authentication vulnerability in Elfatek Elektronics ANKA JPD-00028 allows Authentication Bypass. This issue affects ANKA JPD-00028: before V.01.01.

Improper Error Handling in inSCADA

Improper Protection for Outbound Error Messages and Alert Signals vulnerability in ProMIS Process Co. InSCADA allows Account Footprinting. This issue affects inSCADA: before 20230115-1.

openssh: missing sanitisation of input for X11 forwarding

Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions.

openssh: Prevent connection slot exhaustion attacks

The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections.

openssh: Public key information leak

OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product

ZDI-CAN-20712: Adobe Acrobat Blacklist Bypass Design flaw

Adobe Acrobat Reader versions 23.003.20244 (and earlier) and 20.005.30467 (and earlier) are affected by an Violation of Secure Design Principles vulnerability that could result in arbitrary code execution in the context of the current user by bypassing the API blacklisting feature. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Schneider Electric Floating License Manager Unquoted Search Path or Element

Unquoted Windows search path vulnerability in Schneider Electric Floating License Manager 1.0.0 through 1.4.0 allows local users to gain privileges via a Trojan horse application with a name composed of an initial substring of a path that contains a space character.

The RPC portmapper service is running.

An SNMP community name is the default (e.g. public), null, or missing.

IP forwarding is enabled on a machine which is not a router or firewall.

pinctrl: single: fix refcount leak in pcs_add_gpio_func()

In the Linux kernel, the following vulnerability has been resolved: pinctrl: single: fix refcount leak in pcs_add_gpio_func() of_parse_phandle_with_args() returns a device_node pointer with refcount incremented in gpiospec.np. The loop iterates through all phandles but never releases the reference, causing a refcount leak on each iteration. Add of_node_put() calls to release the reference after extracting the needed arguments and on the error path when devm_kzalloc() fails. This bug was detected by our static analysis tool and verified by my code review.

Adobe Acrobat Reader DC CSP Bypass Leads To Privilege Escalation

Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) is affected by a violation of secure design principles through bypassing the content security policy, which could result in an attacker sending arbitrarily configured requests to the cross-origin attack target domain. Exploitation requires user interaction in which the victim needs to access a crafted PDF file on an attacker's server.

Privilege Escalation in CBOT's Chatbot

Generation of Incorrect Security Tokens vulnerability in CBOT Chatbot allows Token Impersonation, Privilege Abuse. This issue affects Chatbot: before Core: v4.0.3.4 Panel: v4.0.3.7.

Multiple unquoted Windows search path vulnerabilities in the (1) File Collector and (2) File PlaceHolder services in Symantec Enterprise Vault (EV) for File System Archiving before 9.0.4 and 10.x before 10.0.1 allow local users to gain privileges via a Trojan horse program.

Microsoft Terminal Server using Remote Desktop Protocol (RDP) 5.2 stores an RSA private key in mstlsapi.dll and uses it to sign a certificate, which allows remote attackers to spoof public keys of legitimate servers and conduct man-in-the-middle attacks.

Privilege Escalation in Bookreen

Incomplete List of Disallowed Inputs vulnerability in Unisign Bookreen allows Privilege Escalation. This issue affects Bookreen: before 3.0.0.

regulator: fp9931: Fix PM runtime reference leak in fp9931_hwmon_read()

In the Linux kernel, the following vulnerability has been resolved: regulator: fp9931: Fix PM runtime reference leak in fp9931_hwmon_read() In fp9931_hwmon_read(), if regmap_read() failed, the function returned the error code without calling pm_runtime_put_autosuspend(), causing a PM reference leak.
