EulerOS 2.0 SP11 : vim (EulerOS-SA-2024-2570)

medium Nessus Plugin ID 208357

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the vim packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

Vim is an open source command line text editor. double-free in dialog_changed() in Vim v9.1.0648. When abandoning a buffer, Vim may ask the user what to do with the modified buffer. If the user wants the changed buffer to be saved, Vim may create a new Untitled file, if the buffer did not have a name yet.
However, when setting the buffer name to Unnamed, Vim will falsely free a pointer twice, leading to a double-free and possibly later to a heap-use-after-free, which can lead to a crash. The issue has been fixed as of Vim patch v9.1.0648.(CVE-2024-41965)

Vim is an open source command line text editor. Vim v9.1.0647 has double free in src/alloc.c:616. When closing a window, the corresponding tagstack data will be cleared and freed. However a bit later, the quickfix list belonging to that window will also be cleared and if that quickfix list points to the same tagstack data, Vim will try to free it again, resulting in a double-free/use-after-free access exception.
Impact is low since the user must intentionally execute vim with several non-default flags, but it may cause a crash of Vim. The issue has been fixed as of Vim patch v9.1.0647(CVE-2024-41957)

Tenable has extracted the preceding description block directly from the EulerOS vim security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected vim packages.
