What is CVE-2018-13346?

A flaw in the mpatch_apply function within the mpatch.c file in Mercurial versions before 4.6.1 allows the function to incorrectly process data when the starting point of the fragment exceeds the original data's length. This can lead to unexpected behavior, raising concerns for developers relying on accurate data processing in their version control systems. To protect against this vulnerability, users should ensure they are using the latest version of Mercurial, as updates have addressed this issue.
