Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Use of Uninitialized Variable (CVE-ID: CVE-2024-12085)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to information leak when comparing file checksums. A remote attacker can pass specially crafted data to the daemon and read 1 byte of uninitialized memory from stack.


2) Information disclosure (CVE-ID: CVE-2024-12086)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output by the application when handling checksums. A remote attacker can trick the victim into connecting to an attacker-controlled server and enumerate contents of arbitrary files on the client's machine, basically allowing a rouge server to read contents byte-by-byte of any file on the client's system.

This issue occurs when files are being copied from a client to a server.


3) Path traversal (CVE-ID: CVE-2024-12087)

The vulnerability allows a remote server to write files to arbitrary locations on the system.

The vulnerability exists due to input validation error when using "--inc-recursive" option. A remote attacker can can trick the victim into connecting to a rouge rsync server and write arbitrary files to arbitrary locations on the client system.


4) Path traversal (CVE-ID: CVE-2024-12088)

The vulnerability allows a remote server to write files to arbitrary locations on the system.

The vulnerability exists due to input validation error when using "--safe-links" option. A remote attacker can can trick the victim into connecting to a rouge rsync server and write arbitrary files to arbitrary locations on the client system.
