Details
It was discovered that Vim was incorrectly processing Vim buffers.
An attacker could possibly use this issue to perform illegal memory
access and expose sensitive information. (CVE-2022-0554)
It was discovered that Vim was not properly performing bounds checks
for column numbers when replacing tabs with spaces or spaces with
tabs, which could cause a heap buffer overflow. An attacker could
possibly use this issue to cause a denial of service or execute
arbitrary code. (CVE-2022-0572)
It was discovered that Vim was not properly performing validation of
data that contained special multi-byte characters, which could cause
an out-of-bounds read. An attacker could possibly use this issue to
cause a denial of service. (CVE-2022-0685)
It was discovered that Vim was incorrectly processing data used to
define indentation in a file, which could cause a heap buffer
overflow. An attacker could possibly use this issue to cause a denial
of service. (CVE-2022-0714)
It was discovered that Vim was incorrectly processing certain regular
expression patterns and strings, which could cause an out-of-bounds
read. An attacker could possibly use this issue to cause a denial of
service. (CVE-2022-0729)
It was discovered that Vim was not properly performing bounds checks
when executing spell suggestion commands, which could cause a heap
buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2022-0943)
It was discovered that Vim was incorrectly performing bounds checks
when processing invalid commands with composing characters in Ex
mode, which could cause a buffer overflow. An attacker could possibly
use this issue to cause a denial of service or execute arbitrary
code. (CVE-2022-1616)
It was discovered that Vim was not properly processing latin1 data
when issuing Ex commands, which could cause a heap buffer overflow.
An attacker could possibly use this issue to cause a denial of
service or execute arbitrary code. (CVE-2022-1619)
It was discovered that Vim was not properly performing memory
management when dealing with invalid regular expression patterns in
buffers, which could cause a NULL pointer dereference. An attacker
could possibly use this issue to cause a denial of service.
(CVE-2022-1620)
It was discovered that Vim was not properly processing invalid bytes
when performing spell check operations, which could cause a heap
buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2022-1621)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
vim
-
2:7.4.1689-3ubuntu1.5+esm6
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
