- Summary
- Glibc: integer overflow in __vsyslog_internal()
- Details
-
An integer overflow was found in the _vsysloginternal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a very long message, leading to an incorrect calculation of the buffer size to store the message, resulting in undefined behavior. This issue affects glibc 2.37 and newer.
