USN-5613-2: Vim regression
USN-5613-1 fixed vulnerabilities in Vim. Unfortunately that update failed
to include binary packages for some architectures. This update fixes that
regression.
We apologize for the inconvenience.
Original advisory details:
It was discovered that Vim was not properly performing bounds checks
when executing spell suggestion commands. 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 using freed memory when dealing with
regular expressions through its old regular expression engine. If a user
were tricked into opening a specially crafted file, an attacker could
crash the application, leading to a denial of service, or possibly achieve
code execution. (CVE-2022-1154)
It was discovered that Vim was not properly performing checks on name of
lambda functions. An attacker could possibly use this issue to cause a
denial of service. This issue affected only Ubuntu 22.04 LTS.
(CVE-2022-1420)
It was discovered that Vim was incorrectly performing bounds checks
when processing invalid commands with composing characters in Ex
mode. 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. 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. 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. An attacker could possibly use
this issue to cause a denial of service or execute arbitrary code.
(CVE-2022-1621)
