Title: RSync Daemon Mode Undisclosed Remote Heap Overflow Vulnerability
Severity: CRITICAL
Description:
The rsync program is used to synchronize files and directory structures across a network. It is commonly used to maintain mirrors of ftp sites, often through anonymous access to the rsync server. It is available for Linux and other Unix operating systems.
rsync has been reported prone to an undisclosed heap overflow vulnerability when running in daemon mode. The issue has been reported to be remotely exploitable and will provide for an execution of arbitrary code. It has been reported that exploitation of this issue is made easier if the "use chroot = no" option is set in the rsyncd.conf configuration file.
There have been reports that this issue is being exploited in conjunction with the Linux Kernel do_brk function boundary condition vulnerability described in BID 9138. Customers are advised to apply fixes that address the issue described in BID 9138.
This BID will be updated as further information regarding this vulnerability is disclosed.
This vulnerability has been reported to affect rsync version 2.5.6 and earlier versions.
