CVE-2024-43790

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.

This update for vim fixes the following issues:

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).
• CVE-2025-24014: NULL pointer dereference may lead to segmentation fault when in silent Ex mode (bsc#1236151).
• CVE-2025-1215: memory corruption when manipulating the --log argument (bsc#1237137).
