Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-05-18 21:34:06 UTC
From https://github.com/libtom/libtomcrypt/blob/54e6db588a96fe8d29984033c56d105babc88210/changes#L1
      -- Fix Side Channel Based ECDSA Key Extraction (CVE-2018-12437) (PR #408)
      -- Fix potential stack overflow when DER flexi-decoding (CVE-2018-0739) (PR #373)

These were fixed in 1.18.2 (1st July 2018), but the bundled version in net-misc/dropbear is 1.18.1 (22nd Jan 2018): https://github.com/mkj/dropbear/blob/e612aec5d9f25a7334d9e2981f1aabf12b889b64/libtomcrypt/changes#L1
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-05-18 21:39:25 UTC
We can either update the bundled version or just package it in tree finally.
Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-06-15 19:59:09 UTC
From 2020.79 release notes:
"scp fix for CVE-2018-20685 where a server could modify name of output files"
Comment 3 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-06-26 22:50:38 UTC
Note that 2020.79 bumps the bundled versions, so we can do that for now.
