Hvězdička u CVE znamená, že jsem to číslo vytáhl z širšího textu článku.
Neukazuju u něj proto KEV, EPSS ani CVSS, a to preventivně, protože článek se na něj mohl
jen odkazovat, třeba jako na starší kauzu.

Citrix ha rilasciato aggiornamenti di sicurezza per risolvere 3 vulnerabilità, di cui una con gravità "alta", in UniconOS, sistema operativo per endpoint precedentemente noto come "eLux", utilizzato principalmente in ambienti di virtualizzazione desktop (VDI/DaaS). Tale vulnerabilità, qualora sfruttata, potrebbe consentire ad un attaccante locale, autenticato con privilegi limitati, di elevare i propri privilegi sul sistema interessato.
Risolte 4 vulnerabilità con gravità "alta" in XenServer, hypervisor basato su Xen che permette di creare, eseguire e gestire macchine virtuali su un server fisico. Tali vulnerabilità, qualora sfruttate, potrebbero consentire ad utenti malintenzionati presenti all'interno di macchine virtuali guest di causare interruzioni del servizio o compromettere il sistema host, aggirando le restrizioni di sicurezza.
De multiples vulnérabilités ont été découvertes dans les produits Citrix. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire, une élévation de privilèges et un déni de service à distance.

Citrix has warned IT administrators to patch systems immediately against a new critical vulnerability affecting NetScaler ADC networking appliances and NetScaler Gateway secure remote access solutions. [...]
Citrix heeft een kwetsbaarheid verholpen in NetScaler ADC en Gateway producten wanneer deze zijn geconfigureerd als SAML Service Provider (SP) of Identity Provider (IdP). De kwetsbaarheid betreft een geheugenoverflow die optreedt tijdens de verwerking van SAML. Deze kan op afstand worden geactiveerd, waardoor een aanvaller willekeurige code kan uitvoeren of een denial of service kan veroorzaken. De kwetsbaarheid ontstaat door onjuiste geheugenafhandeling tijdens SAML-verwerking.
Welcome to this week’s edition of the Threat Source newsletter. My name is Pierre Cadieux, and I’ll be helping contribute to these newsletters. A little about me: I’ve been working in the cybersecurity industry in many roles over the past 20+ years, first focusing on endpoint security, policies, and firewalls, then moving to risk management and compliance, disaster recovery, and investigations. I spent about 15 years as a consultant working across many well-known consultancy firms and…
Citrix confirmed late on Friday that it was “tracking a newly observed issue” related to some customer-managed NetScaler deployments but claimed the problem was not connected to vulnerabilities reported last week that also caused alarm among cybersecurity experts.
Citrix heeft een kwetsbaarheid verholpen in NetScaler ADC en NetScaler Gateway. De kwetsbaarheid betreft een geheugenoverflow in versies van NetScaler ADC en NetScaler Gateway die ouder zijn dan 14.1-73.41 en 13.1-64.28. Deze kwetsbaarheid kan leiden tot een Denial of Service (DoS) waarbij de normale beschikbaarheid van de dienst wordt verstoord.
