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)
