Linux-PAM 安全漏洞

Linux-pam is a pluggable-supported system authentication software for Linux from the Linux-pam team. A security vulnerability exists in Linux-PAM that allows a local attacker to exploit the vulnerability to set quotas on arbitrary filesystems, in some cases the home directory of the attacker to...

Privilege Escalation

linux-pam:edge is vulnerable to Privilege Escalation. A flaw is found in the way it handles empty passwords for non-existing users. When the user doesn't exist PAM try to authenticate with root and in the case of an empty password it successfully authenticate...

Security Bulletin: IBM Verify Gateway PAM components default to cleartext storage of client secret (CVE-2020-4369)

Summary The IBM Verify Gateway IVG PAM components allow encryption of the client-secret property in the /etc/pamibmauth.json file, but it's not the default configuration. Instead, customers must remember to add an --obfuscation command-line flag to encrypt the property. As of v1.0.1 of IVG for AI...

Security Bulletin: IBM Verify Gateway does not prevent excessive authentication attempts (CVE-2020-4400)

Summary The IBM Verify Gateway IVG components do not prevent rapid, excessive attempts to authenticate with a time-based one-time password TOTP. Consequently, an attacker could brute force account credentials. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and...

Security Bulletin: IBM Verify Gateway PAM components include a leftover debug file (CVE-2020-4371)

Summary The IBM Verify Gateway IVG PAM components include a leftover header file in their installation packages. The file was needed for debugging during development and shouldn't be part of the delivered PAM components. As of v1.0.1 of IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM, the file h...
