DSA-4371-1 apt -- säkerhetsuppdatering

Rapporterat den:
2019-01-22
Berörda paket:
apt
Sårbara:
Ja
Referenser i säkerhetsdatabaser:
I Mitres CVE-förteckning: CVE-2019-3462.
Ytterligare information:

Max Justicz upptäckte en sårbarhet i högnivåpakethanteraren APT. Koden som hanterar HTTP-omdirigeringar i HTTP-transportmetoden rengör inte fält som överförs via anslutningen ordentligt. Denna sårbarhet kunde användas av en angripare som är placerad som man-in-the-middle mellan APT och en spegling för att injicera illasinnat innehåll i HTTP-anslutningen. Detta innehåll skulle sedan komma att kännas igen som ett giltigt paket av APT och användas senare för kodexekvering med rooträttigheter på målmaskinen.

Eftersom sårbarheten finns i pakethanteraren själv rekommenderas det att inaktivera omdirigeringar för att undvika att exploatera felet under dess uppdatering, mha:

apt -o Acquire::http::AllowRedirect=false update
apt -o Acquire::http::AllowRedirect=false upgrade

Detta är känt att det kan bryta några proxies när de används mot security.debian.org. Om detta händer kan folk byta sin security APT-källa till att använda:

deb http://cdn-fastly.deb.debian.org/debian-security stable/updates main

För den stabila utgåvan (Stretch) har detta problem rättats i version 1.4.9.

Vi rekommenderar att ni uppgraderar era apt-paket.

Specifika uppgraderingsinstruktioner::

Om uppgraderingar med hjälp av APT utan omdirigeringar inte är möjligt i din situation kan du manuellt hämta filerna (med hjälp av wget/curl) för din arkitektur med hjälp av URLerna nedan, och verifiera att kontrollsummorna stämmer. Sedan kan du installera dessa med hjälp av dpkg -i.
