Description

This security bulletin contains information about 2 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2025-10158)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to perform a denial of service attack.

The vulnerability exists due to a boundary condition within the send_files() function in sender.c. A remote user can trigger an out-of-bounds read error and perform a denial of service attack.


2) Use-after-free (CVE-ID: CVE-2026-41035)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service and disclose sensitive information.

The vulnerability exists due to use-after-free in receive_xattr() in xattrs.c when processing xattr data from a malicious rsync sender. A remote attacker can send specially crafted xattr metadata to cause a denial of service and disclose sensitive information.

Exploitation requires xattr transfer to be enabled. On Linux, additional conditions apply: the receiver must use --fake-super or an xattr filter that passes non-user namespace xattrs; on FreeBSD and macOS, configurations using xattrs are affected when more than one xattr is processed.
