According to the versions of the vim packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
Vim is an improved version of the good old UNIX editor Vi. Heap-use-after-free in memory allocated in the function ga_grow_inner
in in the file src/alloc.c
at line 748, which is freed in the file src/ex_docmd.c
in the function do_cmdline
at line 1010 and then used again in src/cmdhist.c
at line 759. When using the :history
command, it’s possible that the provided argument overflows the accepted value. Causing an Integer Overflow and potentially later an use-after-free. This vulnerability has been patched in version 9.0.2068. (CVE-2023-46246)
Use After Free in GitHub repository vim/vim prior to 9.0.1840. (CVE-2023-4733)
Integer Overflow or Wraparound in GitHub repository vim/vim prior to 9.0.1846. (CVE-2023-4734)
Out-of-bounds Write in GitHub repository vim/vim prior to 9.0.1847. (CVE-2023-4735)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1848. (CVE-2023-4738)
Use After Free in GitHub repository vim/vim prior to 9.0.1857. (CVE-2023-4750)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1331. (CVE-2023-4751)
Use After Free in GitHub repository vim/vim prior to 9.0.1858. (CVE-2023-4752)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1873. (CVE-2023-4781)
Vim is an open source command line text editor. When closing a window, vim may try to access already freed window structure. Exploitation beyond crashing the application has not been shown to be viable. This issue has been addressed in commit 25aabc2b
which has been included in release version 9.0.2106. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48231)
Vim is an open source command line text editor. If the count after the :s command is larger than what fits into a (signed) long variable, abort with e_value_too_large. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit ac6378773
which has been included in release version 9.0.2108. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48233)
Vim is an open source command line text editor. When getting the count for a normal mode z command, it may overflow for large counts given. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit 58f9befca1
which has been included in release version 9.0.2109. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48234)
Vim is an open source command line text editor. When parsing relative ex addresses one may unintentionally cause an overflow. Ironically this happens in the existing overflow check, because the line number becomes negative and LONG_MAX - lnum will cause the overflow. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit 060623e
which has been included in release version 9.0.2110. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48235)
Vim is an open source command line text editor. When using the z= command, the user may overflow the count with values larger than MAX_INT. Impact is low, user interaction is required and a crash may not even happen in all situations. This vulnerability has been addressed in commit 73b2d379
which has been included in release version 9.0.2111. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48236)
Vim is an open source command line text editor. In affected versions when shifting lines in operator pending mode and using a very large value, it may be possible to overflow the size of integer. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit 6bf131888
which has been included in version 9.0.2112. Users are advised to upgrade.
There are no known workarounds for this vulnerability. (CVE-2023-48237)
Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a :s
command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive :s
call causes free-ing of memory which may later then be accessed by the initial :s
command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue. (CVE-2023-48706)
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.1969. (CVE-2023-5344)
NULL Pointer Dereference in GitHub repository vim/vim prior to 20d161ace307e28690229b68584f2d84556f8960.
(CVE-2023-5441)
Use After Free in GitHub repository vim/vim prior to v9.0.2010. (CVE-2023-5535)
