dovecot: Dovecot: Denial of Service via IMAP ID command with excessive parameters

A flaw was found in Dovecot. An unauthenticated attacker can send an IMAP ID command with a very large number of parameters before logging in. This action causes the server to consume excessive memory and CPU resources, leading to the termination of login processes and other active connections...

rsyslog: A configuration-dependent issue in rsyslog's optional imptcp input module can allow an unauthenticated remote peer to crash rsyslogd

A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code...

Expression Language Injection

Overview org.hibernate.validator:hibernate-validator is a Hibernate Validator Engine Relocation Artifact. Affected versions of this package are vulnerable to Expression Language Injection in the ParameterTermResolver class, whose resolveExpression method converts a message parameter value to a...

CVE-2026-102592

Impact Synapse's mitigation for malicious "multipart/form-data" requests see https://github.com/element-hq/synapse/security/advisories/GHSA-rfq8-j7rh-8hf2 can be bypassed by varying the case of the "Content-Type" header. When processing such a maliciously-crafted request, Synapse quickly exhausts...

EUVD-2026-97667

Zebra before 6.4.0 contains an uncontrolled resource consumption vulnerability that allows unauthenticated peers to force full proof verification by serving forged block bodies with valid header hashes. Attackers can flip authorizing-only bytes such as a coinbase scriptSig, wasting Sapling,...

CVE-2026-109363 Zebra 6.4.0 before 6.4.2 Denial of Service via Malformed v6 Transaction

ZcashFoundation Zebra 6.4.0 before 6.4.2 parses version 6 transactions carrying a pre-NU6.3 consensus branch ID, but the size computation during UnminedTx construction treats re-serialization of the Orchard bundle as infallible, so the resulting error trips an expect that aborts zebrad...

CVE-2026-109363

The ZcashFoundation Zebra software (versions 6.4.0 before 6.4.2 ) is vulnerable to a Denial of Service (DoS) attack. The root cause is that the software parses version 6 transactions with a pre-NU6.3 consensus branch ID but incorrectly treats the re-serialization of the Orchard bundle as infallib...
