Summary:

Several security issues were fixed in Vim.

Software Description:

Details:

It was discovered that Vim was using uninitialized memory when fuzzy
matching, which could lead to invalid memory access. An attacker could
possibly use this issue to cause a denial of service or execute arbitrary
code. This issue only affected Ubuntu 22.04 LTS, Ubuntu 22.10 and Ubuntu
23.04. (CVE-2023-2426)

It was discovered that Vim was not properly performing bounds checks when
processing register contents, which could lead to a NULL pointer
dereference. An attacker could possibly use this issue to cause a denial
of service or execute arbitrary code. (CVE-2023-2609)

It was discovered that Vim was not properly limiting the length of
substitution expression strings, which could lead to excessive memory
consumption. An attacker could possibly use this issue to cause a denial
of service. (CVE-2023-2610)
