- Update to 6.4.20: [bsc#1188875, CVE-2021-36386]
* CVE-2021-36386: DoS or information disclosure in some configurations.
When a log message exceeds c. 2 kByte in size, for instance,
with very long header contents, and depending on verbosity
option, fetchmail can crash or misreport each first log message
that requires a buffer reallocation. fetchmail then reallocates
memory and re-runs vsnprintf() without another call to va_start(),
so it reads garbage. The exact impact depends on many factors
around the compiler and operating system configurations used and
the implementation details of the stdarg.h interfaces of the two
functions mentioned before.
