-
- Updated kernel packages are now available that fix a security
- vulnerability which may allow local users to gain root privileges.
-
- The Linux kernel handles the basic functions of the operating system.
-
- Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux
- kernel versions 2.4.23 and previous which may allow a local attacker to
- gain root privileges. No exploit is currently available; however, it is
- believed that this issue is exploitable (although not trivially.) The
- Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
- the name CAN-2003-0985 to this issue.
-
- All users are advised to upgrade to these errata packages, which contain a
- backported security patch that corrects this issue.
-
- Red Hat would like to thank Paul Starzetz from ISEC for disclosing this
- issue as well as Andrea Arcangeli and Solar Designer for working on the
- patch.
