A vulnerability has been found in Linux-PAM, allowing attackers to bypass the authentication process.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| sys-libs/pam | * | < 1.5.1 | >= 1.5.1 |
Linux-PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes.
A flaw was found in Linux-Pam in the way it handle empty passwords for non-existing users.
A remote attacker, who only needs to know a non-existing username, could bypass security restrictions and authenticate as root user.
Ensure that root account is protected by a non-empty password.
All Linux-PAM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/pam-1.5.1"
Multiple vulnerabilities have been found in Linux-PAM, allowing remote attackers to bypass the auth process and cause Denial of Service.
| Package | Arch | Vulnerable | Unaffected |

| sys-libs/pam | * | < 1.2.1 | >= 1.2.1 |
Linux-PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes.
Multiple vulnerabilities have been discovered in Linux-PAM. Please review the CVE identifiers referenced below for details.
Remote attackers could cause Denial of Service, conduct brute force attacks, and conduct username enumeration.
There is no known workaround at this time.
All Linux-PAM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/pam-1.2.1"
Multiple vulnerabilities have been found in Linux-PAM, allowing local attackers to possibly gain escalated privileges, cause a Denial of Service, corrupt data, or obtain sensitive information.

| sys-libs/pam | * | < 1.1.5 | >= 1.1.5 |
Linux-PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes.
Multiple vulnerabilities have been discovered in Linux-PAM. Please review the CVE identifiers referenced below for details.
A local attacker could use specially crafted files to cause a buffer overflow, possibly resulting in privilege escalation or Denial of Service. Furthermore, a local attacker could execute specially crafted programs or symlink attacks, possibly resulting in data loss or disclosure of sensitive information.
There is no known workaround at this time.
All Linux-PAM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/pam-1.1.5"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since November 25, 2011. It is likely that your system is already no longer affected by this issue.
An error in the handling of user names of Linux-PAM might allow remote attackers to cause a Denial of Service or escalate privileges.

| sys-libs/pam | * | < 1.0.4 | >= 1.0.4 |
Linux-PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes.
Marcus Granado repoted that Linux-PAM does not properly handle user names that contain Unicode characters. This is related to integer signedness errors in the pam_StrTok() function in libpam/pam_misc.c.
A remote attacker could exploit this vulnerability to cause a Denial of Service. A remote authenticated attacker could exploit this vulnerability to log in to a system with the account of a user that has a similar user name, but with non-ASCII characters.
There is no known workaround at this time.
All Linux-PAM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/pam-1.0.4"
A vulnerability in the SELinux version of PAM allows a local attacker to brute-force system passwords.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| sys-libs/pam | * | < 0.78-r3 | >= 0.78-r3 |
PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes. SELinux is an operating system based on Linux which includes Mandatory Access Control.
The SELinux patches for PAM introduce a vulnerability allowing a password to be checked with the unix_chkpwd utility without delay or logging. This vulnerability doesn't affect users who do not run SELinux.
A local attacker could exploit this vulnerability to brute-force passwords and escalate privileges on an SELinux system.
There is no known workaround at this time.
All SELinux PAM users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/pam-0.78-r3"
