high Tenable Cloud Security Plugin ID 478361

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - rsync before 3.5.2 contains a denial of service vulnerability in the delta-transfer sender's hash_search()
 in match.c that allows malicious receivers to trigger unbounded strong-checksum work at consecutive
 offsets. Unauthenticated attackers pulling from a public daemon module can supply weak checksums colliding
 with consecutive rolling windows plus non-matching strong checksums, exhausting sender CPU across
 concurrent connections. (CVE-2026-119741)

Update the rsync library and its related packages to version 3.5.1+ds1-2+e2 or later.
