The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6793-1 advisory.
It was discovered that Git incorrectly handled certain submodules. An attacker could possibly use this issue to execute arbitrary code. This issue was fixed in Ubuntu 22.04 LTS, Ubuntu 23.10 and Ubuntu 24.04 LTS. (CVE-2024-32002)
It was discovered that Git incorrectly handled certain cloned repositories. An attacker could possibly use this issue to execute arbitrary code. (CVE-2024-32004)
It was discovered that Git incorrectly handled local clones with hardlinked files/directories. An attacker could possibly use this issue to place a specialized repository on their target's local system.
(CVE-2024-32020)
It was discovered that Git incorrectly handled certain symlinks. An attacker could possibly use this issue to impact availability and integrity creating hardlinked arbitrary files into users repository's objects/directory. (CVE-2024-32021)
It was discovered that Git incorrectly handled certain cloned repositories. An attacker could possibly use this issue to execute arbitrary code. (CVE-2024-32465)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
