The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has e2fsprogs packages installed that are affected by multiple vulnerabilities:
An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. (CVE-2019-5094)
A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4.
A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. (CVE-2019-5188)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
