-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4614-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso February 01, 2020 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : sudo CVE ID : CVE-2019-18634 Debian Bug : 950371 Joe Vennix discovered a stack-based buffer overflow vulnerability in sudo, a program designed to provide limited super user privileges to specific users, triggerable when configured with the "pwfeedback" option enabled. An unprivileged user can take advantage of this flaw to obtain full root privileges. Details can be found in the upstream advisory at https://www.sudo.ws/alerts/pwfeedback.html . For the oldstable distribution (stretch), this problem has been fixed in version 1.8.19p1-2.1+deb9u2. For the stable distribution (buster), exploitation of the bug is prevented due to a change in EOF handling introduced in 1.8.26. We recommend that you upgrade your sudo packages. For the detailed security status of sudo please refer to its security tracker page at: https://security-tracker.debian.org/tracker/sudo Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@xxxxxxxxxxxxxxxx -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAl41cVhfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0QaKg//TnJPVomILAWCWCSHNUuzuH9c0tBli4KtTw+5QeFwcAeareJbleatZqJh CHi9WI8Dl7nnE0V1mKOgE1pXhrV1WJQrMHidocDo7Aejiyn4EU31HxHsAYv+RvqN E4nNRckP1PEoL9JpGHUMOI3O8mvB+2Nnds0ihy8P+WcZxlxVw+CQuK2omFBhdlwr pgdfBq3khgz5mBx5pzdxIrs9fgJA5Txr+LaOHm06ZL9cP1FTcBK31t1RllKy4bjK bg+igCLVTTqU/8Sydc65UM+rHgx4ljG7bCFWJ3GuRJeeXm1vavfjmCXh8x2ezd3K EsB+FxHDdGpKqwi4bFqWUjijOqaElqAAu/q+xZYzzXZSfIynB5YNfL8tVuq4fsL3 MQdUU/0fZZD5RJW5B2uxppVoHZ15IhG2kRqZK4unCzCcwmXdgKTM+eA6wEp0ib7o Ol3mAWIdUcYzDuKFZU1Ry+62Przm9NX0XXh86Hrigk1oEWcq0iusgGiPPgp4j0mF JjTXAU2fdR5abzLCxkMDKiv+2UnU93/V+4JBLrTijWal2zl9DwD0i+OQVK9ZNxW1 mgj+n7D5iyDNF9ptkP3/0hiL1ITHpWhcbEBAYaNFLD1kv3brNGMNsZzpIXVC6NU9 2KK/2DNyetqnZkmNOt0JQ+G0JFyfouauXi1qr0qCc8PK/f5mLBQ= =d97L -----END PGP SIGNATURE-----
