GLSA-202405-22 : rsync: Multiple Vulnerabilities
high Nessus Plugin ID 195162
Language:
Description
The remote host is affected by the vulnerability described in GLSA-202405-22 (rsync: Multiple Vulnerabilities)- zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)
- A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in- the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using rsync-ssl. The highest threat from this vulnerability is to data confidentiality and integrity. This flaw affects rsync versions before 3.2.4. (CVE-2020-14387)
- An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
All rsync users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose >=net-misc/rsync-3.2.5_pre1
