Dnsmasq: dnsmasq: tcp/53 child-slot exhaustion starves dnssec validation

A flaw was found in dnsmasq. The TCP DNS service uses a small fixed pool of child processes and does not set a receive timeout on client connections. A remote attacker can open idle TCP connections to port 53 and occupy the entire pool, preventing new TCP DNS connections and DNSSEC validation that requires TCP fallback. UDP DNS resolution continues, and occupied slots are released after a fixed lifetime.

Dnsmasq: dnsmasq: heap out-of-bounds write in dnssec validator via to_wire/from_wire transforms

A flaw was found in dnsmasq. After a reduction of internal domain-name buffer sizes, the DNSSEC validator can write a few bytes past a name buffer when converting names to and from DNS wire format. An attacker who can cause the server to validate a crafted DNSSEC response may overwrite a small amount of adjacent heap metadata. DNSSEC support is not compiled in by default and must also be enabled at runtime.

OpenEMR Before 8.5.0 SQL Injection via form_icd_codes[]

OpenEMR before 8.5.0 contains an authenticated SQL injection vulnerability in the Syndromic Surveillance module that allows users with Clinician-level privileges to read and modify arbitrary database contents by submitting crafted values in the form_icd_codes[] POST parameter to the syndromicsurveillance/index endpoint. Attackers can inject an unquoted numeric IN() clause and UNION DISTINCT SELECT statement using hex-encoded literals to abuse MySQL extractvalue() for error-based exfiltration of bcrypt password hashes and execute stacked queries that reset passwords, resulting in full administrative account takeover.

Dnsmasq: dnsmasq: out-of-bailiwick cache injection through cname chase in split-dns configurations

A flaw was found in dnsmasq. When following a CNAME in a DNS response, the resolver can cache records for the CNAME target without checking that those records belong to the responding server's authorized zone. In split-DNS deployments that send some domains to a specific upstream, an attacker who controls that upstream can inject cache entries for unrelated names. Later clients may then receive attacker-chosen addresses for those names.

UpdraftPlus: WP Backup & Migration Plugin <= 1.26.4 - Unauthenticated Authentication Bypass via UpdraftCentral udrpc

The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.26.4 via the UpdraftPlus_Remote_Communications_V2::wp_loaded function. This is due to insufficient validation of the remote communications message format, where signature verification can be bypassed and unchecked decryption return values collapse to a predictable all-zero encryption key. This makes it possible for unauthenticated attackers to forge arbitrary RPC commands and run them as the connected administrator, such as uploading and activating a malicious plugin, which ultimately leads to remot
