Advanced Package Tool Security Vulnerabilities

CVE-2009-1300

apt 0.7.20 does not check when the date command returns an "invalid date" error, which can prevent apt from loading security updates in time zones for which DST occurs at midnight.

CVE-2009-1358

apt-get in apt before 0.7.21 does not check for the correct error code from gpgv, which causes apt to treat a repository as valid even when it has been signed with a key that has been revoked or expired, which might allow remote attackers to trick apt into installing malicious repositories.

CVE-2011-1829

APT before 0.8.15.2 does not properly validate inline GPG signatures, which allows man-in-the-middle attackers to install modified packages via vectors involving lack of an initial clearsigned message.

CVE-2011-3374

It was found that apt-key in apt, all versions, do not correctly validate gpg keys with the master keyring, leading to a potential man-in-the-middle attack.

CVE-2011-3634

methods/https.cc in apt before 0.8.11 accepts connections when the certificate host name fails validation and Verify-Host is enabled, which allows man-in-the-middle attackers to obtain repository credentials via unspecified vectors.

CVE-2012-0214

The pkgAcqMetaClearSig::Failed method in apt-pkg/acquire-item.cc in Advanced Package Tool (APT) 0.8.11 through 0.8.15.10 and 0.8.16 before 0.8.16~exp13, when updating from repositories that use InRelease files, allows man-in-the-middle attackers to install arbitrary packages by preventing a user fr...

CVE-2012-0954

APT 0.7.x before 0.7.25 and 0.8.x before 0.8.16, when using the apt-key net-update to import keyrings, relies on GnuPG argument order and does not check GPG subkeys, which might allow remote attackers to install altered packages via a man-in-the-middle (MITM) attack. NOTE: this vulnerability exists...

CVE-2012-0961

Apt 0.8.16~exp5ubuntu13.x before 0.8.16~exp5ubuntu13.6, 0.8.16~exp12ubuntu10.x before 0.8.16~exp12ubuntu10.7, and 0.9.7.5ubuntu5.x before 0.9.7.5ubuntu5.2, as used in Ubuntu, uses world-readable permissions for /var/log/apt/term.log, which allows local users to obtain sensitive shell information by...

CVE-2012-3587

APT 0.7.x before 0.7.25 and 0.8.x before 0.8.16, when using the apt-key net-update to import keyrings, relies on GnuPG argument order and does not check GPG subkeys, which might allow remote attackers to install Trojan horse packages via a man-in-the-middle (MITM) attack.

CVE-2013-1051

apt 0.8.16, 0.9.7, and possibly other versions does not properly handle InRelease files, which allows man-in-the-middle attackers to modify packages before installation via unknown vectors, possibly related to integrity checking and the use of third-party repositories.

CVE-2014-0478

APT before 1.0.4 does not properly validate source packages, which allows man-in-the-middle attackers to download and install Trojan horse packages by removing the Release signature.

CVE-2014-0487

APT before 1.0.9 does not verify downloaded files if they have been modified as indicated using the If-Modified-Since header, which has unspecified impact and attack vectors.

CVE-2014-0488

APT before 1.0.9 does not "invalidate repository data" when moving from an unauthenticated to authenticated state, which allows remote attackers to have unspecified impact via crafted repository data.

CVE-2014-0489

APT before 1.0.9, when the Acquire::GzipIndexes option is enabled, does not validate checksums, which allows remote attackers to execute arbitrary code via a crafted package.

CVE-2014-0490

The apt-get download command in APT before 1.0.9 does not properly validate signatures for packages, which allows remote attackers to execute arbitrary code via a crafted package.

CVE-2014-6273

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 service (crash) or possibly execute arbitrary code via a crafted URL.

CVE-2014-7206

The changelog command in Apt before 1.0.9.2 allows local users to write to arbitrary files via a symlink attack on the changelog file.

CVE-2016-1252

The apt package in Debian jessie before 1.0.9.8.4, in Debian unstable before 1.4~beta2, in Ubuntu 14.04 LTS before 1.0.1ubuntu2.17, in Ubuntu 16.04 LTS before 1.2.15ubuntu0.2, and in Ubuntu 16.10 before 1.3.2ubuntu0.1 allows man-in-the-middle attackers to bypass a repository-signing protection mech...

CVE-2018-0501

The mirror:// method implementation in Advanced Package Tool (APT) 1.6.x before 1.6.4 and 1.7.x before 1.7.0~alpha3 mishandles gpg signature verification for the InRelease file of a fallback mirror, aka mirrorfail.

CVE-2019-3462

Incorrect sanitation of the 302 redirect field in HTTP transport method of apt versions 1.4.8 and earlier can lead to content injection by a MITM attacker, potentially leading to remote code execution on the target machine.

CVE-2020-27350

APT had several integer overflows and underflows while parsing .deb packages, aka GHSL-2020-168 GHSL-2020-169, in files apt-pkg/contrib/extracttar.cc, apt-pkg/deb/debfile.cc, and apt-pkg/contrib/arfile.cc. This issue affects: apt 1.2.32ubuntu0 versions prior to 1.2.32ubuntu0.2; 1.6.12ubuntu0 versio...

CVE-2020-27351

Various memory and file descriptor leaks were found in apt-python files python/arfile.cc, python/tag.cc, python/tarfile.cc, aka GHSL-2020-170. This issue affects: python-apt 1.1.0~beta1 versions prior to 1.1.0~beta1ubuntu0.16.04.10; 1.6.5ubuntu0 versions prior to 1.6.5ubuntu0.4; 2.0.0ubuntu0 versio...
