SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the e2fsprogs packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- The e2fsprogs package contains a number of utilities for creating, checking, modifying, and correcting any inconsistencies in second, third and fourth extended (ext2/ext3/ext4) filesystems. E2fsprogs contains e2fsck (used to repair filesystem inconsistencies after an unclean shutdown), mke2fs (used to initialize a partition to contain an empty ext2 filesystem), debugfs (used to examine the internal structure of a filesystem, to manually repair a corrupted filesystem, or to create test cases for e2fsck), tune2fs (used to modify filesystem parameters), and most of the other core ext2fs filesystem utilities.
- You should install the e2fsprogs package if you need to manage the performance of an ext2, ext3, or ext4 filesystem.
- Security Fix(es)
- Heap-based buffer overflow in closefs.c in the libext2fs library in e2fsprogs before 1.42.12 allows local users to execute arbitrary code by causing a crafted block group descriptor to be marked as dirty.
NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0247.(CVE-2015-1572)
- Heap-based buffer overflow in openfs.c in the libext2fs library in e2fsprogs before 1.42.12 allows local users to execute arbitrary code via crafted block group descriptor data in a filesystem image.(CVE-2015-0247)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected e2fsprogs packages.
