Vulnerability from certfr_avis - Published: - Updated:
De multiples vulnérabilités ont été découvertes dans Linux PAM. Elles permettent à un utilisateur malveillant d'élever ses privilèges et de dévoiler des informations sensibles.
Description
Les vulnérabilités découvertes dans Linux PAM sont les suivantes :
- une erreur dans le module pam_mail permet de vérifier la présence de certains courriels ;
- une erreur dans le module pam_env permet à un utilisateur malveillant d'afficher un fichier arbitraire situé sur le système ;
- une erreur dans le module pam_namespace permet à un utilisateur malveillant d'élever ses privilèges.
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
Linux PAM versions antérieures à 1.1.3.

CVE-2010-3430 (GCVE-0-2010-3430)
Vulnerability from cvelistv5 – Published: 2011-01-24 17:00 – Updated: 2024-08-07 03:11

VEX
Summary
The privilege-dropping implementation in the (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) 1.1.2 does not perform the required setfsgid and setgroups system calls, which might allow local users to obtain sensitive information by leveraging unintended group permissions, as demonstrated by a symlink attack on the .pam_environment file in a user's home directory. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-3435.

Summary
The (1) pam_env and (2) pam_mail modules in Linux-PAM (aka pam) before 1.1.2 use root privileges during read access to files and directories that belong to arbitrary user accounts, which might allow local users to obtain sensitive information by leveraging this filesystem activity, as demonstrated by a symlink attack on the .pam_environment file in a user's home directory.
Severity
No CVSS data available.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
