In Spring Boot versions 3.0.0 - 3.0.6, 2.7.0 - 2.7.11, 2.6.0 - 2.6.14, 2.5.0 - 2.5.14 and older unsupported versions, there is potential for a denial-of-service (DoS) attack if Spring MVC is used together with a reverse proxy cache. Specifically, an application is vulnerable if all of the conditions are true: * The application has Spring MVC auto-configuration enabled. This is the case by default if Spring MVC is on the classpath. * The application makes use of Spring Boot's welcome page support, either static or templated. * Your application is deployed behind a proxy which caches 404 responses. Your application is NOT vulnerable if any of the following are true: * Spring MVC auto-configuration is disabled. This is true if WebMvcAutoConfiguration is explicitly excluded, if Spring MVC is not on the classpath, or if spring.main.web-application-type is set to a value other than SERVLET. * The application does not use Spring Boot's welcome page support. * You do not have a proxy which...

A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may allow an authenticated client to cause a denial of service.

In Cloud foundry routing release versions from 0.262.0 and prior to 0.266.0,a bug in the gorouter process can lead to a denial of service of applications hosted on Cloud Foundry. Under the right circumstances, when client connections are closed prematurely, gorouter marks the currently selected backend as failed and removes it from the routing pool.

Categories: Exploits and vulnerabilities Categories: News Zyxel has released a security advisory about two critical vulnerabilities that could allow an unauthorized, remote attacker to take control of its firewall devices. (Read more...) The post Zyxel patches two critical vulnerabilities appeared first on Malwarebytes Labs.

Debian Linux Security Advisory 5411-1 - Multiple issues were found in GPAC multimedia framework, which could result in denial of service or potentially the execution of arbitrary code.

Ubuntu Security Notice 6109-1 - Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service. Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information.

c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1.

Those using HtmlUnit to browse untrusted webpages may be vulnerable to Denial of service attacks (DoS). If HtmlUnit is running on user supplied web pages, an attacker may supply content that causes HtmlUnit to crash by a stack overflow. This effect may support a denial of service attack. This issue affects HtmlUnit before 2.70.0.

Ubuntu Security Notice 6108-1 - It was discovered that Jhead did not properly handle certain crafted images while rotating them. An attacker could possibly use this issue to crash Jhead, resulting in a denial of service. Kyle Brown discovered that Jhead did not properly handle certain crafted images while regenerating the Exif thumbnail. An attacker could possibly use this issue to execute arbitrary commands.
