Title
Multiple vulnerabilities in Limesurvey
Summary
Vulnerability in LimeSurvey 6.13.0 in the endpoint /optin that causes infinite HTTP redirects when accessed directly. This behavior can be exploited to generate a Denegation of Service (DoS attack), by exhausting server or client resources. The system is unable to break the redirect loop, which can cause service degradation or browser instability.

Title
ts-asn1-der has Incorrect DER Encoding of Numbers Leading to Denial of Service and Incorrect Value Representation
Summary
ts-asn1-der is a collection of utility classes to encode ASN.1 data following DER rule. Incorrect number DER encoding can lead to denial on service for absolute values in the range 2**31 -- 2**32 - 1. The arithmetic in the numBitLen didn't take into account that values in this range could result in a negative result upon applying the >> operator, leading to an infinite loop. The issue is patched in version 1.0.4. If upgrading is not an option, the issue can be mitigated by validating inputs to Asn1Integer to ensure that they are not smaller than -2**31 + 1 and no larger than 2**31 - 1.

Title
Denial of service via crafted DoH exchange in PowerDNS DNSdist
Summary
In some circumstances, when DNSdist is configured to use the nghttp2 library to process incoming DNS over HTTPS queries, an attacker might be able to cause a denial of service by crafting a DoH exchange that triggers an unbounded I/O read loop, causing an unexpected consumption of CPU resources.

Title
GeoServer has an Infinite Loop Vulnerability in Jiffle process
Summary
GeoServer is an open source server that allows users to share and edit geospatial data. Malicious Jiffle scripts can be executed by GeoServer, either as a rendering transformation in WMS dynamic styles or as a WPS process, that can enter an infinite loop to trigger denial of service. This vulnerability is fixed in 2.27.0, 2.26.3, and 2.25.7. This vulnerability can be mitigated by disabling WMS dynamic styling and the Jiffle process.

Title
Azle calling `setTimer` causes infinite loop of timers
Summary
Azle is a WebAssembly runtime for TypeScript and JavaScript on ICP. Calling `setTimer` in Azle versions `0.27.0`, `0.28.0`, and `0.29.0` causes an immediate infinite loop of timers to be executed on the canister, each timer attempting to clean up the global state of the previous timer. The infinite loop will occur with any valid invocation of `setTimer`. The problem has been fixed as of Azle version `0.30.0`. As a workaround, if a canister is caught in this infinite loop after calling `setTimer`, the canister can be upgraded and the timers will all be cleared, thus ending the loop.

Summary
Loop with unreachable exit condition ('infinite loop') for some Intel(R) Platform within Ring 0: Kernel may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

CVE-2025-27497 (GCVE-0-2025-27497)

Title
OpenDJ Denial of Service (Dos) using alias loop
Summary
OpenDJ is an LDAPv3 compliant directory service. OpenDJ prior to 4.9.3 contains a denial-of-service (DoS) vulnerability that causes the server to become unresponsive to all LDAP requests without crashing or restarting. This issue occurs when an alias loop exists in the LDAP database. If an ldapsearch request is executed with alias dereferencing set to "always" on this alias entry, the server stops responding to all future requests. Fortunately, the server can be restarted without data corruption. This vulnerability is fixed in 4.9.3.
