Red Hat Security Advisory: RHSA-2005:105-01 - Updated Perl packages fix
security issues
Detail
======
Perl is a high-level programming language commonly used for system
administration utilities and Web programming.
Kevin Finisterre discovered a stack based buffer overflow flaw in sperl,
the Perl setuid wrapper. A local user could create a sperl executable
script with a carefully created path name, overflowing the buffer and
leading to root privilege escalation. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0156
to this issue.
Kevin Finisterre discovered a flaw in sperl which can cause debugging
information to be logged to arbitrary files. By setting an environment
variable, a local user could cause sperl to create, as root, files with
arbitrary filenames, or append the debugging information to existing
files. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2005-0155 to this issue.
