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.

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.
An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.
A possible memory corruption due to a type confusion was found in the Linux kernel in the skclonelock() function in the net/core/sock.c. A possibility of local escalation of privileges cannot be fully ruled out for a local unprivileged attacker.

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 heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the gescapeuristring() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
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 flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.
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
Reference: https://github.com/squid-cache/squid/security/advisories/GHSA-phqj-m8gv-cq4g
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.
A missing bounds check was found in the way OpenSSL handled TLS heartbeat extension packets. This flaw could be used to reveal up to 64k of memory from a connected client or server.
Only 1.0.1 releases of OpenSSL are affected including 1.0.1f (and 1.0.2 betas)
The following upstream commit introduced TLS/DTLS heatbeat support and also this issue:
http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=4817504
apache. Multiple issues were addressed by updating to version 2.4.27.
Withdrawn Advisory This advisory has been withdrawn because the vulnerability only affects the Qpid Proton C library and not org.apache.qpid:proton-j. This link has been maintained to preserve external references.
Original Description
While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS even when configured to verify the peer certificate while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic.
It was discovered that the JNDI comment of OpenJDK did not properly enforce the restriction controlled by the com.sun.jndi.ldap.object.trustURLCodebase system property. In certain cases, a Java LDAP client could unexpectedly load and execute code form an LDAP server.
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBCTUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBCTUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
A flaw was found in Yelp. The Gnome user help application allows the help document to execute arbitrary scripts. This vulnerability allows malicious users to input help documents, which may exfiltrate user files to an external environment.
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copypagetoiterpipe and pushpipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
