A flaw was found in the Apache Commons BeanUtils, where the class property in PropertyUtilsBean is not suppressed by default. This flaw allows an attacker to access the classloader.
A flaw was found in Node.js versions before 6.15.0, 8.14.0, 10.14.0 and 11.3.0. A Denial of Service with large HTTP headers. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic
A malicious web application running on Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 was able to bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet.
A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
A null pointer dereference vulnerability was found in the certificate parsing code in Python. This causes a denial of service to applications when parsing specially crafted certificates. This vulnerability is unlikely to be triggered if application enables SSL/TLS certificate validation and accepts certificates only from trusted root certificate authorities.
A flaw in Node.js HTTP request handling causes an uncaught TypeError when a request is received with a header named proto and the application accesses req.headersDistinct.
When this occurs, dest["proto"] resolves to Object.prototype rather than undefined, causing .push() to be called on a non-array. This exception is thrown synchronously inside a property getter and cannot be intercepted by error event listeners, meaning it cannot be handled without wrapping every req.headersDistinct access in a try/catch.
This vulnerability affects all Node.js HTTP servers on 20.x, 22.x, 24.x, and v25.x
A heap-buffer-overflow vulnerability exists in the APNG (Animated PNG) file loader of GIMP. This flaw occurs when the fcTL width exceeds the IHDR width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the loadlayer() function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution.
A race condition was found in the way Linux kernel's memory subsystem handled breakage of the read only private mappings COW situation on write access.
An unprivileged local user could use this flaw to gain write access to otherwise read only memory mappings and thus increase their privileges on the system.
Red Hat is aware of this issue and if you have questions about the affectedness of your system please contact Red Hat Support. For additional information see https://access.redhat.com/security/vulnerabilities/2706661

A vulnerability identified in NetIQ Advance Authentication that leaks sensitive server information. This issue affects NetIQ Advance Authentication version before 6.3.5.1
Accessibility. A logic issue was addressed with improved checks.
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
Artifex Ghostscript allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile.
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
A flaw in the Linux Kernel found. If unprivileged users can mount FUSE filesystems, then can trigger use after free (UAF) that reads of write() buffers, allowing theft of (partial) /etc/shadow hashes or any other data from filesystem.
FUSE allows the userspace filesystem to specify on FUSEOPEN whether the file should use the normal kernel pagecache for handling read()/write() or just send FUSEREAD/FUSEWRITE requests directly to the userspace filesystem (using the flag FOPENDIRECTIO in fuseopenout::openflags).
In FOPENDIRECTIO mode, fusefilewriteiter() calls fusedirectwriteiter(), which normally calls fusedirectio(), which then imports the write buffer with fusegetuserpages(), which uses iovitergetpages() to grab references to userspace pages instead of actually copying memory.
On the filesystem device side, these pages can then either be read to userspace (via fusedevread()), or splice()d over into a pipe using fusedevspliceread() as pipe buffers with &nostealpipebufops.
This is wrong because after fusedevdoread() unlocks the FUSE request, the userspace filesystem can mark the request as completed, causing write() to return. At that point, the write buffer may be reused for other purposes, and the userspace filesystem should no longer have access to it.

A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.
A Local Privilege Escalation vulnerability (from any user to root) was found in polkit's pkexec, a SUID-root program that is installed by default on every major Linux distribution.
A flaw was found in libsoup. The package is vulnerable to a heap buffer over-read when sniffing content via the skipinsightwhitespace() function. Libsoup clients may read one byte out-of-bounds in response to a crafted HTTP response by an HTTP server.
A vulnerability was found in Buildah. Cache mounts do not properly validate that user-specified paths for the cache are within our cache directory, allowing a RUN instruction in a Container file to mount an arbitrary directory from the host (read/write) into the container as long as those files can be accessed by the user running Buildah.
Description: Due to a buffer overflow bug Squid is vulnerable to a Denial of Service attack against HTTP Digest Authentication

Affected versions: 3.2.0.1-5.9, 6.0-6.3
A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.
A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution.
