Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2024-12084)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling checksum lengths (s2length). A remote attacker can send specially crafted packets to the daemon, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) 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.
3) 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.
4) 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.
5) Path traversal (CVE-ID: CVE-2024-12088)
The vulnerability allows a remote server to write files to arbitrary locations on the system.
