CVE-2014-0487
HighSummary
APT versions before 1.0.9 do not verify downloaded files if they have been modified as indicated by the If-Modified-Since header. This can lead to unspecified impacts and attack vectors.
Risk Assessment
The lack of verification for downloaded files poses a risk that malicious or unauthorized files may be accepted by the system, potentially leading to security compromises.
Recommendation
It is recommended to update APT to version 1.0.9 or later to ensure proper verification of downloaded files.
Other vulnerabilities in APT
See all- CVE-2014-0489High
APT versions before 1.0.9, when the Acquire::GzipIndexes option is enabled, do not validate checksums, allowing remote attackers to execute arbitrary code via a crafted package.
- CVE-2026-109518High
On Debian, Ubuntu, and derivative Linux distributions, an on-path attacker who can manipulate the HTTP traffic (including a malicious mirror or proxy) between an APT client and an archive server triggered by a package install can trick the client into installing an attacker-controlled unverified package and achieve remote code execution with root privileges. The vulnerability is caused by the reuse of hard links and requires the client to follow redirects and retry the download of package files. It requires the client to have a non-zero Acquire::Retries configuration setting; the value 3 is the default starting with Debian 12 (bookworm) and Ubuntu 22.04 LTS (Jammy Jellyfish), so older releases are unaffected in a default configuration.
