An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of service (unbounded recursion) via a nested Netlink policy with a back reference.

Ubuntu Security Notice 5971-1 - It was discovered that graphviz contains null pointer dereference vulnerabilities. Exploitation via a specially crafted input file can cause a denial of service. This issue only affected Ubuntu 18.04 LTS. It was discovered that graphviz contains null pointer dereference vulnerabilities. Exploitation via a specially crafted input file can cause a denial of service. These issues only affected Ubuntu 14.04 ESM and Ubuntu 18.04 LTS.

Ubuntu Security Notice 5970-1 - It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service.

Ubuntu Security Notice 5969-1 - It was discovered that gif2apng contained multiple heap-base overflows. An attacker could potentially exploit this to cause a denial of service.

Debian Linux Security Advisory 5377-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

In Spring Framework versions 6.0.0 - 6.0.6, 5.3.0 - 5.3.25, 5.2.0.RELEASE - 5.2.22.RELEASE, and older unsupported versions, it is possible for a user to provide a specially crafted SpEL expression that may cause a denial-of-service (DoS) condition.

A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 ("net: sched: fix race condition in qdisc_graft()") not applied yet, then kernel could be affected.

### Impact Affected versions of [net.minidev:json-smart](https://github.com/netplex/json-smart-v1) are vulnerable to Denial of Service (DoS) due to a StackOverflowError when parsing a deeply nested JSON array or object. When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively. It was discovered that the 3PP does not have any limit to the nesting of such arrays or objects. Since the parsing of nested arrays and objects is done recursively, nesting too many of them can cause stack exhaustion (stack overflow) and crash the software. ### Patches This vulnerability was fixed in json-smart version 2.4.9, but the maintainer recommends upgrading to 2.4.10, due to a remaining bug. ### Workarounds N/A ### References - https://www.cve.org/CVERecord?id=CVE-2023-1370 - https://nvd.nist.gov/vuln/detail/CVE-2023-1370 - https://security.snyk.io/vuln/SNYK-JAVA-NETMINIDEV-3369748

A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to a segmentation fault, generating many trash files in "/tmp," resulting in a denial of service. When ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will generate about 10G.
