netty-incubator-codec-ohttp: Binary HTTP parser unchecked varint length overflow causes decoder crash

Summary io.netty.incubator:netty-incubator-codec-bhttp uses attacker-controlled Binary HTTP variable-length integers as long values but accumulates them into int offsets. Large valid varint lengths wrap the internal offset negative, leading to unchecked ArrayIndexOutOfBoundsException /...

Wagtail: Denial of service via unbounded filter specs in the image preview

Impact An authenticated admin user can trigger expensive rendition processing with purposefully crafted filter specs resulting in potentially service degradation. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. Patches Patched versions have be...

netty-incubator-codec-ohttp: [OHttpServerCodec] Native Direct-Memory Leak on AEAD Decryption Failure Leads to Gateway Denial of Service

The netty-incubator-codec-ohttp library implements Oblivious HTTP OHTTP gateway and client functionality using Netty's ByteBuf memory management. When an OHTTP gateway processes encrypted client requests, it allocates a pooled direct native off-heap ByteBuf to hold the decrypted plaintext before...

Laravel Backpack CRUD: OS command injection in Stats::makeCurlRequest via attacker-controlled Host header (pre-auth)

Summary Backpack\CRUD\Stats::makeCurlRequest builds a shell command using unescaped input that originates from the HTTP Host header, then passes it to exec. A specially crafted Host header can break out of the shell argument and cause the server to execute arbitrary OS commands as the web user. T...

httpd: mod_md: unrestricted OCSP response leads to resource exhaustion

A flaw was found in the modmd module of httpd. When processing OCSP Online Certificate Status Protocol responses from a malicious or compromised OCSP responder, the module fails to enforce proper size limits on the incoming data. This issue leads to memory exhaustion and a denial of service...

GHSA-22W5-2FXG-VRWX OpenTofu has high CPU usage when using K8S remote state backend or when parsing specifically crafted TLS certificates from untrusted or compromised servers

Impact Unauthenticated denial of service. Summary When OpenTofu performs requests against an untrusted or compromised third-party server or connects to an attacker-controlled server, the initial connection negotiation can produce high CPU usage, leading to possible denial of service. These...

Zoo Design Studio: Recursive KCL parsing is vulnerable to denial-of-service

Impact Feeding a KCL program that wraps an expression in deep, unnecessary parentheses triggers the parser’s recursive expression - unnecessarilybracketed - expression path. With enough nesting, the call stack grows until it exceeds the process stack limit, causing a stack overflow...

postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...

Important: Red Hat Security Advisory: postgresql security update

An update for postgresql is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is...

CVE-2026-63495

Libevent is an event notification library. From 2.2.0-alpha-dev until 2.2.2-alpha, the libevent WebSocket server in ws.c accumulates fragmented frames in evws-incompleteframes without enforcing a total message-size limit. An unauthenticated remote client can repeatedly send fragmented WebSocket...

CVE-2026-63384

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in eventtagging.c when evtagunmarshalheader uses evtagdecodeint to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INTMAX becom...

CVE-2026-74340

A flaw was found in the Linux kernel's wcn36xx Wi-Fi driver. The driver uses a firmware-controlled count to access a memory buffer without proper validation of the count's value. A malicious or malformed firmware response could provide an excessive count, leading to an out-of-bounds read from the...

CVE-2026-74335

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs in the bpftaskfromvpid function when a cgroupskb program, running in a soft interrupt, attempts to look up a task that is in the process of exiting. If the task's process ID PID namespace is...

urwid: Urwid: Predictable session IDs lead to remote code execution and information disclosure

A flaw was found in the urwid web display backend. This vulnerability arises from the use of a cryptographically insecure pseudo-random number generator PRNG for web session identifiers, making them predictable. An attacker could either observe enough session IDs to reconstruct the PRNG state or,...

RLSA-2026:56971 Important: perl-Date-Manip security update

Date::Manip is a series of modules designed to make any common date/time operation easy to do. Operations such as comparing two times, determining a data a given amount of time from another, or parsing international times are all easily done. It deals with time as it is used in the Gregorian...
