sys-libs/pam*< 1.5.1>= 1.5.1

Background

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.

Description

A flaw was found in Linux-Pam in the way it handle empty passwords for non-existing users.

Impact

A remote attacker, who only needs to know a non-existing username, could bypass security restrictions and authenticate as root user.

Workaround

Ensure that root account is protected by a non-empty password.

Resolution

All Linux-PAM users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/pam-1.5.1"

sys-libs/pam*< 1.1.5>= 1.1.5

Background

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.

Description

Multiple vulnerabilities have been discovered in Linux-PAM. Please review the CVE identifiers referenced below for details.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

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.

sys-libs/pam*< 1.0.4>= 1.0.4

Background

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.

Description

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.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All Linux-PAM users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/pam-1.0.4"

sys-libs/pam*< 0.78-r3>= 0.78-r3

Background

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.

Description

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.

Impact

A local attacker could exploit this vulnerability to brute-force passwords and escalate privileges on an SELinux system.

Workaround

There is no known workaround at this time.

Resolution

All SELinux PAM users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/pam-0.78-r3"
