Vulnerability from certfr_avis - Published: 2021-12-07 - Updated: 2021-12-07

De multiples vulnérabilités ont été découvertes dans les produits GitLab. Certaines d'entre elles permettent à un attaquant de provoquer un déni de service, un contournement de la politique de sécurité et une atteinte à l'intégrité des données.

L'éditeur a également mis à jour les composants tiers suivants pour corriger des vulnérabilités présentes dans leurs versions antérieures : Ruby, Rails, ncurses, libgcrypt, mattermost, graphql, mermaid.
