EulerOS 2.0 SP12 : rsync (EulerOS-SA-2026-2566)

medium Nessus Plugin ID 326192

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the rsync packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended buffer bounds.
 Attackers can exploit this vulnerability to disclose process memory contents including environment variables, passwords, heap and stack data, and library memory pointers, significantly reducing ASLR effectiveness and facilitating further exploitation.(CVE-2026-43618)

 In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.(CVE-2026-41035)

Tenable has extracted the preceding description block directly from the EulerOS rsync security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected rsync packages.
