Title
Libxml2: memory leak leading to local denial of service in xmllint interactive shell
Summary
A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to free the allocated buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system memory and terminate the xmllint process, creating a denial-of-service condition on the local system.

CVE-2026-0992 (GCVE-0-2026-0992)

Vulnerability from cvelistv5 – Published: 2026-01-15 14:20 – Updated: 2026-01-15 16:39

Title
Libxml2: libxml2: denial of service via crafted xml catalogs
Summary
A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.
Severity ?
2.9 (Low)

CVE-2026-0989 (GCVE-0-2026-0989)

Title
Libxml2: unbounded relaxng include recursion leading to stack overflow
Summary
A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.
Severity ?

Title
Libxml2: libxml2: denial of service via uncontrolled recursion in xml catalog processing
Summary
A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.

This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications."

CVE-2025-6170 (GCVE-0-2025-6170)

Title
Libxml2: stack buffer overflow in xmllint interactive shell command handling
Summary
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
Severity ?

CVE-2024-10306 (GCVE-0-2024-10306)

Vulnerability from cvelistv5 – Published: 2025-04-23 09:59 – Updated: 2025-11-08 07:11
VLAI?
Title
Mod_proxy_cluster: mod_proxy_cluster unauthorized mcmp requests
Summary
A vulnerability was found in mod_proxy_cluster. The issue is that the <Directory> directive should be replaced by the <Location> directive as the former does not restrict IP/host access as `Require ip IP_ADDRESS` would suggest. This means that anyone with access to the host might send MCMP requests that may result in adding/removing/updating nodes for the balancing. However, this host should not be accessible to the public network as it does not serve the general traffic.
Severity ?
