Util-Linux Security Vulnerabilities - February

CVE-2001-1147

The PAM implementation in /bin/login of the util-linux package before 2.11 causes a password entry to be rewritten across multiple PAM calls, which could provide the credentials of one user to a different user, when used in certain PAM modules such as pam_limits.

CVE-2001-1175

vipw in the util-linux package before 2.10 causes /etc/shadow to be world-readable in some cases, which would make it easier for local users to perform brute force password guessing.

CVE-2003-0094

A patch for mcookie in the util-linux package for Mandrake Linux 8.2 and 9.0 uses /dev/urandom instead of /dev/random, which causes mcookie to use an entropy source that is more predictable than expected, which may make it easier for certain types of attacks to succeed.

CVE-2004-0080

The login program in util-linux 2.11 and earlier uses a pointer after it has been freed and reallocated, which could cause login to leak sensitive data.

CVE-2005-2876

umount in util-linux 2.8 to 2.12q, 2.13-pre1, and 2.13-pre2, and other packages such as loop-aes-utils, allows local users with unmount permissions to gain privileges via the -r (remount) option, which causes the file system to be remounted with just the read-only flag, which effectively clears the...

CVE-2006-7108

login in util-linux-2.12a skips pam_acct_mgmt and chauth_tok when authentication is skipped, such as when a Kerberos krlogin session has been established, which might allow users to bypass intended access policies that would be enforced by pam_acct_mgmt and chauth_tok.
