Buffer overflow in the HTTP transport code in apt-get in APT 1.0.1 and earlier allows man-in-the-middle attackers to cause a denial of servi
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 2.4% (FIRST EPSS); higher than 83.9% of all records.
- Fixed version: apt (Debian:12) 1.0.3; apt (Debian:6.0) 0.8.10.3+squeeze5; apt (Debian:7) 0.9.7.9+deb7u5.
Low priority for now. Upgrade to apt (Debian:12) 1.0.3; apt (Debian:6.0) 0.8.10.3+squeeze5; apt (Debian:7) 0.9.7.9+deb7u5 or later.
