Created attachment 226760 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D226760&action= =3Dedit /usr/ports update to take fetchmail to v6.4.20 Hi Corey, please review and if possible approve of the attached port update to fetchm= ail v6.4.20 to address a security vulnerability in some configurations. vuxml entry already committed (not yet rendered): https://cgit.freebsd.org/ports/commit/?id=3Db913df304c485ba61fc981f7e633b96= d4b3ea492 release notes: ---------------------------------------------------------------------------= ------ fetchmail-6.4.20 (released 2021-07-28, 30042 LoC): # SECURITY FIX:=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 * When a log message exceeds c. 2 kByte in size, for instance, with very lo= ng 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. To fix CVE-2021-38386.
