CVE-2021-43172 1 Nlnetlabs 1 Routinator 2024-11-21 7.5 High
NLnet Labs Routinator prior to 0.10.2 happily processes a chain of RRDP repositories of infinite length causing it to never finish a validation run. In RPKI, a CA can choose the RRDP repository it wishes to publish its data in. By continuously generating a new child CA that only consists of another CA using a different RRDP repository, a malicious CA can create a chain of CAs of de-facto infinite length. Routinator prior to version 0.10.2 did not contain a limit on the length of such a chain and will therefore continue to process this chain forever. As a result, the validation run will never finish, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all.
CVE-2021-42715 3 Debian, Fedoraproject, Nothings 3 Debian Linux, Fedora, Stb Image.h 2024-11-21 5.5 Medium
An issue was discovered in stb stb_image.h 1.33 through 2.27. The HDR loader parsed truncated end-of-file RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused denial of service in applications using stb_image by submitting crafted HDR files.
CVE-2021-42694 1 Unicode 1 Unicode 2024-11-21 8.3 High
An issue was discovered in the character definitions of the Unicode Specification through 14.0. The specification allows an adversary to produce source code identifiers such as function names using homoglyphs that render visually identical to a target identifier. Adversaries can leverage this to inject code via adversarial identifier definitions in upstream software dependencies invoked deceptively in downstream software. NOTE: the Unicode Consortium offers the following alternative approach to presenting this concern. An issue is noted in the nature of international text that can affect applications that implement support for The Unicode Standard (all versions). Unless mitigated, an adversary could produce source code identifiers using homoglyph characters that render visually identical to but are distinct from a target identifier. In this way, an adversary could inject adversarial identifier definitions in upstream software that are not detected by human reviewers and are invoked deceptively in downstream software. The Unicode Consortium has documented this class of security vulnerability in its document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode Security Mechanisms.
CVE-2021-42574 4 Fedoraproject, Redhat, Starwindsoftware and 1 more 10 Fedora, Devtools, Enterprise Linux and 7 more 2024-11-21 8.3 High
An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the following alternative approach to presenting this concern. An issue is noted in the nature of international text that can affect applications that implement support for The Unicode Standard and the Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-right and right-to-left characters, the visual order of tokens may be different from their logical order. Additionally, control characters needed to fully support the requirements of bidirectional text can further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such that the ordering of tokens perceived by human reviewers does not match what will be processed by a compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
CVE-2021-42084 1 Zammad 1 Zammad 2024-11-21 6.5 Medium
An issue was discovered in Zammad before 4.1.1. An attacker with valid agent credentials may send a series of crafted requests that cause an endless loop and thus cause denial of service.
CVE-2021-42040 1 Mediawiki 1 Mediawiki 2024-11-21 7.5 High
An issue was discovered in MediaWiki through 1.36.2. A parser function related to loop control allowed for an infinite loop (and php-fpm hang) within the Loops extension because egLoopsCountLimit is mishandled. This could lead to memory exhaustion.
CVE-2021-41973 2 Apache, Oracle 9 Mina, Banking Payments, Banking Trade Finance Process Management and 6 more 2024-11-21 6.5 Medium
In Apache MINA, a specifically crafted, malformed HTTP request may cause the HTTP Header decoder to loop indefinitely. The decoder assumed that the HTTP Header begins at the beginning of the buffer and loops if there is more data than expected. Please update MINA to 2.1.5 or greater.
CVE-2021-41079 4 Apache, Debian, Netapp and 1 more 6 Tomcat, Debian Linux, Management Services For Element Software And Netapp Hci and 3 more 2024-11-21 7.5 High
Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.
CVE-2021-40839 2 Fedoraproject, Rencode Project 2 Fedora, Rencode 2024-11-21 7.5 High
The rencode package through 1.0.6 for Python allows an infinite loop in typecode decoding (such as via ;\x2f\x7f), enabling a remote attack that consumes CPU and memory.
CVE-2021-40592 1 Gpac 1 Gpac 2024-11-21 5.5 Medium
GPAC version before commit 71460d72ec07df766dab0a4d52687529f3efcf0a (version v1.0.1 onwards) contains loop with unreachable exit condition ('infinite loop') vulnerability in ISOBMFF reader filter, isoffin_read.c. Function isoffin_process() can result in DoS by infinite loop. To exploit, the victim must open a specially crafted mp4 file.
CVE-2021-40111 1 Apache 1 James 2024-11-21 6.5 Medium
In Apache James, while fuzzing with Jazzer the IMAP parsing stack, we discover that crafted APPEND and STATUS IMAP command could be used to trigger infinite loops resulting in expensive CPU computations and OutOfMemory exceptions. This can be used for a Denial Of Service attack. The IMAP user needs to be authenticated to exploit this vulnerability. This affected Apache James prior to version 3.6.1. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade.
CVE-2021-3908 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-11-21 5.9 Medium
OctoRPKI does not limit the depth of a certificate chain, allowing for a CA to create children in an ad-hoc fashion, thereby making tree traversal never end.

CVE-2021-3416 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Qemu and 2 more 2024-11-21 6.0 Medium
A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-3128 1 Asus 54 Rt-ac1750 B1, Rt-ac1750 B1 Firmware, Rt-ac1900 and 51 more 2024-11-21 7.5 High
In ASUS RT-AX3000, ZenWiFi AX (XT8), RT-AX88U, and other ASUS routers with firmware < 3.0.0.4.386.42095 or < 9.0.0.4.386.41994, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set.
CVE-2021-3125 1 Tp-link 12 Tl-xdr1850, Tl-xdr1850 Firmware, Tl-xdr1860 and 9 more 2024-11-21 7.5 High

This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set.
