Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Vim is an open source command line text editor. When performing a search and displaying the search-count
    message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer
    (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by
    allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated
    will be smaller than the original allocated buffer (because for allocating the reversed buffer, the
    strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original
    length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the
    previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.
    (CVE-2024-43790)

  - Vim is an improved version of the unix vi text editor. When flushing the typeahead buffer, Vim moves the
    current position in the typeahead buffer but does not check whether there is enough space left in the
    buffer to handle the next characters. So this may lead to the tb_off position within the typebuf variable
    to point outside of the valid buffer size, which can then later lead to a heap-buffer overflow in e.g.
    ins_typebuf(). Therefore, when flushing the typeahead buffer, check if there is enough space left before
    advancing the off position. If not, fall back to flush current typebuf contents. It's not quite clear yet,
    what can lead to this situation. It seems to happen when error messages occur (which will cause Vim to
    flush the typeahead buffer) in comnination with several long mappgins and so it may eventually move the
    off position out of a valid buffer size. Impact is low since it is not easily reproducible and requires to
    have several mappings active and run into some error condition. But when this happens, this will cause a
    crash. The issue has been fixed as of Vim patch v9.1.0697. Users are advised to upgrade. There are no
    known workarounds for this issue. (CVE-2024-43802)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:0723-1 advisory.

    Update to version 9.1.1101:

    - CVE-2024-43790: possible out-of-bounds read when performing a search command (bsc#1229685).
    - CVE-2024-43802: heap buffer overflow due to incorrect flushing of the typeahead buffer (bsc#1229822).
    - CVE-2024-45306: heap buffer overflow when cursor position is invalid (bsc#1230078).
    - CVE-2025-22134: heap buffer overflow when switching to other buffers using the :all command with active     visual mode       (bsc#1235695).

An update of the vim package has been released.

The version of Vim installed on the remote host is after 9.1.0425 and prior to 9.1.0689. It is, therefore, affected by a heap buffer overflow vulnerability.

When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer.
