USN-5458-1: Vim vulnerabilities

Read Time:1 Minute, 38 Second

It was discovered that Vim was incorrectly handling virtual column
position operations, which could result in an out-of-bounds read. An
attacker could possibly use this issue to expose sensitive
information. (CVE-2021-4193)

It was discovered that Vim was not properly performing bounds checks
when updating windows present on a screen, which could result in a
heap buffer overflow. An attacker could possibly use this issue to
cause a denial of service or execute arbitrary code. (CVE-2022-0213)

It was discovered that Vim was incorrectly handling window
exchanging operations when in Visual mode, which could result in an
out-of-bounds read. An attacker could possibly use this issue to
expose sensitive information. (CVE-2022-0319)

It was discovered that Vim was incorrectly handling recursion when
parsing conditional expressions. An attacker could possibly use this
issue to cause a denial of service or execute arbitrary code.
(CVE-2022-0351)

It was discovered that Vim was not properly handling memory
allocation when processing data in Ex mode, which could result in a
heap buffer overflow. An attacker could possibly use this issue to
cause a denial of service or execute arbitrary code.
(CVE-2022-0359)

It was discovered that Vim was not properly performing bounds checks
when executing line operations in Visual mode, which could result in
a heap buffer overflow. An attacker could possibly use this issue to
cause a denial of service or execute arbitrary code.
(CVE-2022-0361, CVE-2022-0368)

It was discovered that Vim was not properly handling loop conditions
when looking for spell suggestions, which could result in a stack
buffer overflow. An attacker could possibly use this issue to cause
a denial of service or execute arbitrary code. (CVE-2022-0408)

Multiple Vulnerabilities in Mozilla Products Could Allow for Arbitrary Code Execution

Read Time:39 Second

Multiple vulnerabilities have been discovered in Mozilla Firefox, Firefox Extended Support Release (ESR) and Mozilla Thunderbird, the most severe of which could allow for arbitrary code execution.

Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Mozilla Thunderbird is an email client

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
