CVE-2017-15298 (GCVE-0-2017-15298)

Vulnerability from cvelistv5 – Published: 2017-10-14 19:00 – Updated: 2024-08-05 19:50

Summary

Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.

Severity

No CVSS data available.
