qt5-qtbase: qt6-qtbase: Qt: Denial of Service vulnerability in XML parsing

A flaw was found in Qt. This vulnerability, specifically an unbounded recursion in the QDomNode destructor during QDomDocument XML parsing, allows a remote attacker to trigger a denial-of-service DoS crash. By processing untrusted XML input, the affected system can become unresponsive, leading to...

By processing untrusted XML input, the affected system can become unresponsive, leading to...

qtbase: qt5-qtbase: qt6-qtbase: qtbase: Denial of Service via uncontrolled recursion in XML serialization

A flaw was found in qtbase. Uncontrolled recursion in Qt's QDomDocument serialization QtXml allows a remote attacker to provide deeply nested untrusted XML, leading to stack exhaustion. This can cause the application to crash, resulting in a Denial of Service DoS...

resolv: resolv gem: Denial of Service via uncontrolled memory growth from crafted DNS responses

A flaw was found in the resolv gem. An attacker controlling DNS responses e.g., a spoofed response or a malicious upstream DNS server can exploit this by sending crafted DNS responses containing many distinct unknown DNS resource record pairs or SvcParamKeys. This leads to uncontrolled memory...

rsyslog: rsyslog: Denial of service via heap buffer overflow in RainerScript replace() function

A flaw was found in rsyslog. An unauthenticated remote attacker can trigger a heap buffer overflow in the RainerScript replace function by sending specially crafted syslog messages. This vulnerability arises from an incorrect buffer size calculation during string replacement, causing memory...

gdb: gdb: Out-of-bounds write in STABS parser read_member_functions() via crafted ELF

A flaw was found in GDB's STABS debug format parser. The readmemberfunctions function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main functio...

ruby: integer overflow issue in CI/CD regular expression compiler

A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, an integer overflow in the size of the compiled pattern can occur. This integer overflow causes memory...

ruby: integer overflow issue in regular expression compiler

A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, an integer overflow in the size of the compiled pattern can occur. This integer overflow causes memory...

ruby: integer overflow issue in regular expression compiler

A flaw was found in Ruby. When compiling a specially crafted regular expression containing an excessive number of repeats with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /input/, an integer overflow of internal IDs can occur. This integer overflow...

resteasy-core: RESTEasy: IIOImageProvider Unbounded Image Decode (Decompression-Bomb DoS)

A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very larg...

resteasy-core: RESTEasy: CorsFilter Reflects Arbitrary Origin with Credentials under Wildcard Config

A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins "", reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...

github.com/labstack/echo: Echo: Unauthorized Information Disclosure via URL Path Decoding Discrepancy

A flaw was found in Echo, a Go web framework. An attacker can exploit a disagreement in URL path decoding between the router and the static file handler. The router processes raw encoded paths, while the static file handler unescapes encoded forward slashes. This allows an attacker to bypass...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references

A flaw was found in crypto/tls. A remote attacker can trigger this vulnerability by sending a specially crafted packet containing multiple Encrypted Client Hello ECH outer extension references to a server. Processing these unauthorized references leads to excessive memory consumption, causing a...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

CVE-2026-123589

The DNS-over-QUIC DoQ server in hickory-server hickory-dns before 0.26.2 does not apply any timeout when reading a request message from a QUIC stream, bypassing all configured timeouts. A remote unauthenticated client can open a connection and a request stream and hold it open indefinitely,...
