Descripción técnica

quirc through 1.2 contains an excessive-iteration vulnerability in find_alignment_pattern() in lib/identify.c that allows attackers to hang quirc_end() with a crafted image. Attackers can arrange three finder patterns producing a near-degenerate perspective transform, causing billions of region_code() iterations that exhaust CPU in applications decoding attacker-supplied QR images.

———A missing circuit-breaker in the replicator in Apache CouchDB 3.5.2 and below on all platforms allows the owner of a replication source or target to cause a denial of service via creating an infinite HTTP redirect loop. Users are recommended to upgrade to version 3.5.3, which fixes this issue.7h CVE-2026-1065765.3 MED

——9ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31, a crafted XMP profile can trigger excessive work while the parser determines a rational value's numerator and denominator, causing denial of service.

——11Improper validation of specified quantity in input, Allocation of resources without limits or throttling, Excessive Iteration vulnerability in Apache Thrift PHP bindings. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.19d CVE-2026-53493—

——8containerd is an open-source container runtime. Prior to versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1, a crafted OCI index graph can force very high CPU/memory usage during PullImage (before container start), causing long ContainerCreating stalls and, at larger sizes, node/runtime instability. Versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1 fix the issue.22d CVE-2026-87721—

——7Uncontrolled Resource Consumption (CWE-400 / CWE-407) in the ANTLR 3 search query parser (QueryParser / Query.g) in Gerrit Code Review versions 2.0.19 through 3.12.9, 3.13.0 through 3.13.8, and 3.14.0 through 3.14.2 allows an unauthenticated remote attacker (or an authenticated user if anonymous read access is disabled) to cause a persistent denial of service (CPU exhaustion and HTTP worker thread pool starvation requiring a server restart) via crafted search queries containing deeply nested parentheses sent to query evaluation endpoints (/changes/?q=, /accounts/?q=, /groups/?query=, /projects/?query=, /Documentation/?q=, /changes/{id}/query?expression=, or SSH gerrit query). Because syntactic predicates in conditionOr and conditionAnd recurse via conditionBase without memoization prior to capability or visibility checks and worker threads do not abort when the client disconnects, a small number of requests (such as 25 requests matching default httpd.maxThreads) can permanently pin all HTTP worker threads. This issue is fixed in Gerrit Code Review versions 3.12.10, 3.13.9, and 3.14.3.25d CVE-2026-773996.5 MED

——7icalendar is an RFC 5545 compatible parser and generator of iCalendar files for Python. From 6.1.0 until 7.2.2, vInt.from_ical accepts an attacker-controlled VALARM REPEAT value and applications that request alarm times can eagerly expand it without an application-level limit. Alarms.times and Alarms.active reach the unbounded expansion in versions starting with 6.1.0, while Alarm.triggers adds a second affected path starting with 7.0.0. Parsing alone does not trigger the issue, but accessing these properties can consume excessive CPU time and heap memory and terminate or stall a service. This issue is fixed in version 7.2.2.27d
