setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file…

An interaction between the Perl MD5 module (perl-Digest-MD5) and Perl could produce incorrect MD5 checksums for UTF-8 data, which could prevent a system from properly verifying the integrity of the data.
