CVE-2023-45862 2 Linux, Netapp 4 Linux Kernel, Active Iq Unified Manager, H410c and 1 more 2024-01-08 N/A 5.5 MEDIUM
An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux kernel before 6.2.5. An object could potentially extend beyond the end of an allocation.
CVE-2023-50730 1 Typelevel 1 Grackle 2024-01-08 N/A 7.5 HIGH
Grackle is a GraphQL server written in functional Scala, built on the Typelevel stack. The GraphQL specification requires that GraphQL fragments must not form cycles, either directly or indirectly. Prior to Grackle version 0.18.0, that requirement wasn't checked, and queries with cyclic fragments would have been accepted for type checking and compilation. The attempted compilation of such fragments would result in a JVM `StackOverflowError` being thrown. Some knowledge of an applications GraphQL schema would be required to construct such a query, however no knowledge of any application-specific performance or other behavioural characteristics would be needed. Grackle uses the cats-parse library for parsing GraphQL queries. Prior to version 0.18.0, Grackle made use of the cats-parse `recursive` operator. However, `recursive` is not currently stack safe. `recursive` was used in three places in the parser: nested selection sets, nested input values (lists and objects), and nested list type declarations. Consequently, queries with deeply nested selection sets, input values or list types could be constructed which exploited this, causing a JVM `StackOverflowException` to be thrown during parsing. Because this happens very early in query processing, no specific knowledge of an applications GraphQL schema would be required to construct such a query. The possibility of small queries resulting in stack overflow is a potential denial of service vulnerability. This potentially affects all applications using Grackle which have untrusted users. Both stack overflow issues have been resolved in the v0.18.0 release of Grackle. As a workaround, users could interpose a sanitizing layer in between untrusted input and Grackle query processing.
CVE-2023-45129 2 Fedoraproject, Matrix 2 Fedora, Synapse 2024-01-07 N/A 4.9 MEDIUM
Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. Prior to version 1.94.0, a malicious server ACL event can impact performance temporarily or permanently leading to a persistent denial of service. Homeservers running on a closed federation (which presumably do not need to use server ACLs) are not affected. Server administrators are advised to upgrade to Synapse 1.94.0 or later. As a workaround, rooms with malicious server ACL events can be purged and blocked using the admin API.
CVE-2023-0809 1 Eclipse 1 Mosquitto 2024-01-07 N/A 5.3 MEDIUM
In Mosquitto before 2.0.16, excessive memory is allocated based on malicious initial packets that are not CONNECT packets.
CVE-2023-3171 1 Redhat 2 Enterprise Linux, Jboss Enterprise Application Platform 2024-01-04 N/A 7.5 HIGH
A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result in a Denial of Service.
CVE-2023-6563 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2023-12-27 N/A 7.7 HIGH
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2023-38532 1 Siemens 2 Parasolid, Teamcenter Visualization 2023-12-22 N/A 5.5 MEDIUM
A vulnerability has been identified in Parasolid V34.1 (All versions < V34.1.258), Parasolid V35.0 (All versions < V35.0.254), Parasolid V35.1 (All versions < V35.1.171), Teamcenter Visualization V14.1 (All versions < V14.1.0.11), Teamcenter Visualization V14.2 (All versions < V14.2.0.6), Teamcenter Visualization V14.3 (All versions < V14.3.0.3). The affected application contains a stack exhaustion vulnerability while parsing a specially crafted X_T file. This could allow an attacker to cause denial of service condition.
CVE-2020-18899 1 Exiv2 1 Exiv2 2023-12-22 4.3 MEDIUM 6.5 MEDIUM
An uncontrolled memory allocation in DataBufdata(subBox.length-sizeof(box)) function of Exiv2 0.27 allows attackers to cause a denial of service (DOS) via a crafted input.
CVE-2023-5379 1 Redhat 3 Jboss Enterprise Application Platform, Single Sign-on, Undertow 2023-12-20 N/A 7.5 HIGH
A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS).
CVE-2023-50247 1 Dena 1 H2o 2023-12-19 N/A 7.5 HIGH
h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. The QUIC stack (quicly), as used by H2O up to commit 43f86e5 (in version 2.3.0-beta and prior), is susceptible to a state exhaustion attack. When H2O is serving HTTP/3, a remote attacker can exploit this vulnerability to progressively increase the memory retained by the QUIC stack. This can eventually cause H2O to abort due to memory exhaustion. The vulnerability has been resolved in commit d67e81d03be12a9d53dc8271af6530f40164cd35. HTTP/1 and HTTP/2 are not affected by this vulnerability as they do not use QUIC. Administrators looking to mitigate this issue without upgrading can disable HTTP/3 support.
CVE-2023-4486 1 Johnsoncontrols 20 F4-snc, F4-snc Firmware, Nae55 and 17 more 2023-12-19 N/A 7.5 HIGH
Under certain circumstances, invalid authentication credentials could be sent to the login endpoint of Johnson Controls Metasys NAE55, SNE, and SNC engines prior to versions 11.0.6 and 12.0.4 and Facility Explorer F4-SNC engines prior to versions 11.0.6 and 12.0.4 to cause denial-of-service.
CVE-2023-46695 1 Djangoproject 1 Django 2023-12-14 N/A 7.5 HIGH
An issue was discovered in Django 3.2 before 3.2.23, 4.1 before 4.1.13, and 4.2 before 4.2.7. The NFKC normalization is slow on Windows. As a consequence, django.contrib.auth.forms.UsernameField is subject to a potential DoS (denial of service) attack via certain inputs with a very large number of Unicode characters.
CVE-2023-5072 1 Json-java Project 1 Json-java 2023-12-13 N/A 7.5 HIGH
Denial of Service in JSON-Java versions up to and including 20230618.  A bug in the parser means that an input string of modest size can lead to indefinite amounts of memory being used. 
CVE-2023-50455 1 Zammad 1 Zammad 2023-12-13 N/A 7.5 HIGH
An issue was discovered in Zammad before 6.2.0. Due to lack of rate limiting in the "email address verification" feature, an attacker could send many requests for a known address to cause Denial Of Service (generation of many emails, which would also spam the victim).
CVE-2023-34389 1 Selinc 2 Sel-451, Sel-451 Firmware 2023-12-10 N/A 6.5 MEDIUM
An allocation of resources without limits or throttling vulnerability in the Schweitzer Engineering Laboratories SEL-451 could allow a remote authenticated attacker to make the system unavailable for an indefinite amount of time. See product Instruction Manual Appendix A dated 20230830 for more details.
CVE-2023-42504 1 Apache 1 Superset 2023-12-10 N/A 6.5 MEDIUM
An authenticated malicious user could initiate multiple concurrent requests, each requesting multiple dashboard exports, leading to a possible denial of service. This issue affects Apache Superset: before 3.0.0
CVE-2023-45371 1 Mediawiki 1 Mediawiki 2023-12-10 N/A 7.5 HIGH
An issue was discovered in the Wikibase extension for MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. There is no rate limit for merging items.
CVE-2023-40019 1 Freeswitch 1 Freeswitch 2023-12-10 N/A 6.5 MEDIUM
FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to version 1.10.10, FreeSWITCH allows authorized users to cause a denial of service attack by sending re-INVITE with SDP containing duplicate codec names. When a call in FreeSWITCH completes codec negotiation, the `codec_string` channel variable is set with the result of the negotiation. On a subsequent re-negotiation, if an SDP is offered that contains codecs with the same names but with different formats, there may be too many codec matches detected by FreeSWITCH leading to overflows of its internal arrays. By abusing this vulnerability, an attacker is able to corrupt stack of FreeSWITCH leading to an undefined behavior of the system or simply crash it. Version 1.10.10 contains a patch for this issue.
CVE-2023-4578 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-12-10 N/A 6.5 MEDIUM
When calling `JS::CheckRegExpSyntax` a Syntax Error could have been set which would end in calling `convertToRuntimeErrorAndClear`. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
CVE-2023-5289 1 Ikus-soft 1 Rdiffweb 2023-12-10 N/A 8.8 HIGH
