Trustix Secure Linux Advisory: rsync

Dec 04, 2003, 21:57 (0 Talkback[s])

Trustix Secure Linux Security Advisory #2003-0048
Package name: rsync
Summary: remote code execution
Date: 2003-12-04
Affected versions: TSL 1.2, 1.5, 2.0

Package description:
Rsync uses a quick and reliable algorithm to very quickly bring remote and host files into sync. Rsync is fast because it just sends the differences in the files over the network (instead of sending the complete files). Rsync is often used as a very powerful mirroring process or just as a more capable replacement for the rcp command. A technical report which describes the rsync algorithm is included in this package.

Problem description:
All versions of rsync prior to 2.5.7 contains a heap overflow that can be used to exceute arbitary code from remote. The Common Vulnerabilites and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0962 to this issue.

We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.
