CVSS v3.1 |
| c-ares is an asynchronous resolver library. From 1.32.3 through 1.34.4, there is a use-after-free in read_answers() when process_answer() may re-enqueue a query either due to a DNS Cookie Failure or when the upstream server does not properly support EDNS, or possibly on TCP queries if the remote closed the connection immediately after a response. If there was an issue trying to put that new transaction on the wire, it would close the connection handle, but read_answers() was still expecting the connection handle to be available to possibly dequeue other responses. In theory a remote attacker might be able to trigger this by flooding the target with ICMP UNREACHABLE packets if they also control the upstream nameserver and can return a result with one of those conditions, this has been untested. Otherwise only a local attacker might be able to change system behavior to make send()/write() return a failure condition. This vulnerability is fixed in 1.34.5. |
| Starting in Python 3.12.0, the asyncio._SelectorSocketTransport.writelines()
method would not "pause" writing and signal to the Protocol to drain
the buffer to the wire once the write buffer reached the "high-water
mark". Because of this, Protocols would not periodically drain the write
buffer potentially leading to memory exhaustion.
This
vulnerability likely impacts a small number of users, you must be using
Python 3.12.0 or later, on macOS or Linux, using the asyncio module
with protocols, and using .writelines() method which had new
zero-copy-on-write behavior in Python 3.12.0 and later. If not all of
these factors are true then your usage of Python is unaffected. |
| A flaw was found in linux-pam. The pam_namespace module may improperly handle user-controlled paths, allowing local users to exploit symlink attacks and race conditions to elevate their privileges to root. This CVE provides a "complete" fix for CVE-2025-6020. |
| The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header which is redirected to b.com/ will not send that header to b.com. In the event that the client received a subsequent same-domain redirect, however, the sensitive headers would be restored. For example, a chain of redirects from a.com/, to b.com/1, and finally to b.com/2 would incorrectly send the Authorization header to b.com/2. |
| gorilla/schema converts structs to and from form values. Prior to version 1.4.1 Running `schema.Decoder.Decode()` on a struct that has a field of type `[]struct{...}` opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of `schema.Decoder.Decode()` on a struct with arrays of other structs could be vulnerable to this memory exhaustion vulnerability. Version 1.4.1 contains a patch for the issue. |
| In the Linux kernel through 6.9, an untrusted hypervisor can inject virtual interrupts 0 and 14 at any point in time and can trigger the SIGFPE signal handler in userspace applications. This affects AMD SEV-SNP and AMD SEV-ES. |
| A cross-privilege Spectre v2 vulnerability allows attackers to bypass all deployed mitigations, including the recent Fine(IBT), and to leak arbitrary Linux kernel memory on Intel systems. |
| The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an "Expect: 100-continue" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending "Expect: 100-continue" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail. |
| A flaw was found in PCP. The default pmproxy configuration exposes the Redis server backend to the local network, allowing remote command execution with the privileges of the Redis user. This issue can only be exploited when pmproxy is running. By default, pmproxy is not running and needs to be started manually. The pmproxy service is usually started from the 'Metrics settings' page of the Cockpit web interface. This flaw affects PCP versions 4.3.4 and newer. |
| The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot find a matching configured secret. When such a connection is automatically added on startup using the auto= keyword, it can cause repeated crashes leading to a Denial of Service. |
| Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors sending emails to a victim, this is a security issue. An external attacker can send specially crafted messages that consume target system resources and cause outage. One can implement restrictions on address headers on MTA component preceding Dovecot. No publicly available exploits are known. |
| A vulnerability in Node.js has been identified, allowing for a Denial of Service (DoS) attack through resource exhaustion when using the fetch() function to retrieve content from an untrusted URL.
The vulnerability stems from the fact that the fetch() function in Node.js always decodes Brotli, making it possible for an attacker to cause resource exhaustion when fetching content from an untrusted URL.
An attacker controlling the URL passed into fetch() can exploit this vulnerability to exhaust memory, potentially leading to process termination, depending on the system configuration. |
| A denial of service vulnerability was found in 389-ds-base ldap server. This issue may allow an authenticated user to cause a server crash while modifying `userPassword` using malformed input. |
| A flaw was found in 389-ds-base. A specially-crafted LDAP query can potentially cause a failure on the directory server, leading to a denial of service |
| Hardware logic with insecure de-synchronization in Intel(R) DSA and Intel(R) IAA for some Intel(R) 4th or 5th generation Xeon(R) processors may allow an authorized user to potentially enable escalation of privilege local access |
| Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. |
| Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. |
| Varnish Cache before 7.6.3 and 7.7 before 7.7.1, and Varnish Enterprise before 6.0.13r14, allow client-side desync via HTTP/1 requests, because the product incorrectly permits CRLF to be skipped to delimit chunk boundaries. |
| With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread is created. This is not limited only to workers but also exposes internal workers, where an instance of them can be fetched, and its constructor can be grabbed and reinstated for malicious usage.
This vulnerability affects Permission Model users (--permission) on Node.js v20, v22, and v23. |
| Calling Decoder.Decode on a message which contains deeply nested structures can cause a panic due to stack exhaustion. This is a follow-up to CVE-2022-30635. |
