CVE Vulnerability Catalog

rsync versions 3.4.2 before 3.5.0 contain a denial of service vulnerability that allows a remote sender to exhaust system resources by specifying the --zt short alias for --compress-threads, which bypasses the refuse options directive's string matching on long option names. Attackers can specify --zt=N with a large value to spawn an unbounded number of Zstandard worker threads on the receiver, exhausting available thread and memory resources.

rsync versions 3.2.0 through 3.2.3 (openssl mode) and rsync-ssl through 3.4.4 (stunnel mode) contain a TLS certificate validation vulnerability that allows on-path attackers to intercept encrypted sessions by presenting self-signed or otherwise invalid certificates. Attackers can exploit the failure to validate server TLS certificates against a trusted CA or verify certificate hostname matching to decrypt or tamper with rsync session content without detection by the client.

Rsync before version 3.5.0 contains an algorithmic complexity vulnerability in the hash_search() function that allows a remote attacker to cause a denial of service by delivering a carefully constructed file list. A sender can exploit the quadratic-time worst-case behavior in hash lookups to exhaust receiver CPU resources with a modest number of crafted entries, causing a sustained denial of service.

rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based deny rule fails, the daemon skips the rule rather than defaulting to a deny decision, enabling attackers who can trigger DNS failures to bypass module-level IP access controls and gain unauthorized access to restricted module file trees.

A potential authentication bypass vulnerability was reported in Lenovo System Update that could allow a local authenticated user to execute arbitrary code with elevated privileges.

In the Linux kernel, in the KVM subsystem for s390 PCI handling, a bug was found: when a guest registers IRQs without a summary bit, the associated GAITE entry stores an incorrect value (physical address instead of zero) in the guest AISB location. The fix ensures zero is stored there.

In the Linux kernel, in the s390/zcrypt subsystem, a buffer over-read vulnerability was found in cca_cipher2protkey. User-controlled length fields in CCA token structures were used without proper validation against buffer size and minimum token size, potentially leading to out-of-bounds reads or buffer underruns, causing kernel crashes or memory exposure.

In the Linux kernel, in the s390/zcrypt subsystem, a missing length validation was found in CCA AES cipher key requests. cca_cipher2protkey() derives the copy length from the key token length field, which could lead to out-of-bounds read if the token length exceeds the available space in the CPRB parameter block.

In the Linux kernel, in the s390/zcrypt subsystem, a missing length validation was found in CCA ECC private key requests. cca_ecc2protkey() derives the copy length from the key token length field, which could lead to out-of-bounds read if the token length exceeds the available space in the CPRB parameter block.

Deserialization of Untrusted Data vulnerability in Apache Shindig. This issue affects Apache Shindig: all versions. Users with access to the Shindig REST API can send specially-crafted requests to trigger arbitrary code execution on the server. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

Passkey entry Bluetooth LE legacy pairing can be bypassed in the RS9116W and SiWx917 by manipulating the temporary key value. See vulnerability B-E3 in the related paper below.

An unencrypted 'pause encryption request' message causes a denial of service in the BT122 module. See vulnerability B-E10 in the related paper below.

During an internal security assessment, a potential vulnerability was discovered in Lenovo Dock Manager that could allow an authenticated local user to perform an arbitrary file deletion with elevated privileges.

During an internal security assessment, a potential improper permissions vulnerability was discovered in Lenovo Dock Manager that could allow a local authenticated user to execute arbitrary code with elevated privileges.

During an internal security assessment, an improperly protected key was discovered in Lenovo Dock Manager that could allow a local authenticated user to escalate privileges.

During an internal security assessment, a potential vulnerability was discovered in Lenovo Accessories and Display Manager for Enterprise for Windows that could allow a local authenticated user to execute arbitrary code with elevated privileges.

rsync before 3.5.0 contains a symlink following vulnerability that allows local attackers to overwrite arbitrary files by placing a symlink at a predictable output path such as --log-file, --write-batch, or daemon-mode log and statistics paths. Attackers can exploit rsync's failure to reject symlinks during ancillary file writes to redirect output to arbitrary filesystem locations, achieving local privilege escalation on installations where rsync runs with elevated privileges such as setuid or privileged daemon configurations.

rsync before 3.5.0 contains an arbitrary file read vulnerability that allows attackers to read files accessible to the rsync daemon process by exploiting symlink following in input configuration file handling including --files-from, --password-file, and filter merge files. Attackers can place a symlink at a predictable --files-from or --password-file path, or supply a --files-from path that escapes the daemon module root, to read arbitrary files accessible to the rsync process.

rsync before 3.5.0 contains an arbitrary file write vulnerability that allows attackers to write files outside the intended destination tree by specifying an absolute path via --temp-dir or --link-dest options. The rename-confinement logic is bypassed when these options resolve to paths outside the destination tree, enabling attacker-controlled values to write files to arbitrary locations accessible to the rsync process.

rsync before 3.5.0 contains a path confinement bypass vulnerability that allows remote clients to escape the intended inner-module root confinement by constructing paths that resolve outside the chroot boundary when the module root contains a /./ boundary marker. Attackers can exploit improper handling of the /./ notation or forge delta-basis transfers referencing xname paths that cross the /./ boundary to gain unauthorized read or write access to files outside the module's subtree.
