A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.

The version of rsync installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-12084 advisory.

    Package        : rsync     Debian Bug     : 1093052 1093089     CVE ID         : CVE-2024-12084 CVE-2024-12085 CVE-2024-12086 CVE-2024-12087                      CVE-2024-12088 CVE-2024-12747

    The update for rsync announced in DSA 5843-1 introduced a regression     when using the -H option to preserve hard links. Updated packages are     now available to correct this issue.

    Several vulnerabilities were discovered in rsync, a fast, versatile,     remote (and local) file-copying tool.

    CVE-2024-12084

        Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a         heap-based buffer overflow vulnerability due to improper handling of         attacker-controlled checksum lengths. A remote attacker can take         advantage of this flaw for code execution.

    CVE-2024-12085

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a flaw in         the way rsync compares file checksums, allowing a remote attacker to         trigger an information leak.

    CVE-2024-12086

        Simon Scannell, Pedro Gallegos and Jasiel Spelman discovered a flaw         which would result in a server leaking contents of an arbitrary file         from the client's machine.

    CVE-2024-12087

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported a path         traversal vulnerability in the rsync daemon affecting the
        --inc-recursive option, which could allow a server to write files         outside of the client's intended destination directory.

    CVE-2024-12088

        Simon Scannell, Pedro Gallegos and Jasiel Spelman reported that when         using the --safe-links option, rsync fails to properly verify if a         symbolic link destination contains another symbolic link with it,         resulting in path traversal and arbitrary file write outside of the         desired directory.

    CVE-2024-12747

        Aleksei Gorban loqpa discovered a race condition when handling         symbolic links resulting in an information leak which may enable         escalation of privileges.

    For the stable distribution (bookworm), these problems have been fixed in     version 3.2.7-1+deb12u2.

    We recommend that you upgrade your rsync packages.
