Comment 1 Lewis Smith 2022-01-30 21:28:02 CET
This package is seldom touched, and has no evident associated packager; so assigning this bug globally.

Comment 2 Nicolas Salguero 2022-01-31 16:03:22 CET
Suggested advisory:
========================

The updated package fixes a security vulnerability:

lrzsz before version 0.12.21~rc can leak information to the receiving side due to an incorrect length check in the function zsdata that causes a size_t to wrap around. (CVE-2018-10195)

MGA8-64Plasma on Lenovo B50 in Dutch
No installation issues.
Serial connection ???? That's ages ago......
Found http://www.armadeus.org/wiki/index.php?title=Serial_Transfer
and that suggests one could use an USB connection between PC's to run this.
But frankly, is it worthwile to spend time to get this ting configured correctly???
I suggest OK on clean install, if TJ or ...... approves.

From https://directory.fsf.org/wiki/Lrzsz

"lrzsz is a unix communication package providing the XMODEM, YMODEM ZMODEM file transfer protocols."

Wow. I don't think I've done anything with those since transferring files from our local user group bbs during my Atari 8-bit computer days 30 years ago. My two laptops both have serial ports, but I don't even know if they work - I've never tried to use them. A serial cable? Maybe, if I looked hard enough, but no device that I know of to connect to any more. Almost seems like I had a null-modem cable once, but if I did I have no idea where it is.

I think we're OK with a clean install. Validating. Advisory in Comment 2.
