CVE-2016-5844

Integer overflow in the ISO parser in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a crafted ISO file.

Integer overflow in the ISO parser in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a crafted ISO file.

These are all security issues fixed in the bsdtar-3.2.2-2.1 package on the GA media of openSUSE Tumbleweed.

This update for libarchive fixes several issues.

These security issues were fixed:

• CVE-2016-8687: Buffer overflow when printing a filename (bsc#1005070).
• CVE-2016-8689: Heap overflow when reading corrupted 7Zip files (bsc#1005072).
• CVE-2016-8688: Use after free because of incorrect calculation in next_line (bsc#1005076).
• CVE-2016-5844: Integer overflow in the ISO parser in libarchive allowed remote attackers to cause a denial of service (application crash) via a crafted ISO file (bsc#986566).
• CVE-2016-6250: Integer overflow in the ISO9660 writer in libarchive allowed remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors related to verifying filename lengths when writing an ISO9660 archive, which trigger a buffer overflow (bsc#989980).
• CVE-2016-5418: The sandboxing code in libarchive mishandled hardlink archive entries of non-zero data size, which might allowed remote attackers to write to arbitrary files via a crafted archive file (bsc#998677).

Hanno Böck discovered that libarchive contained multiple security issues when processing certain malformed archive files. A remote attacker could use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code.

Marcin "Icewall" Noga discovered that libarchive contained multiple security issues when processing certain malformed archive files. A remote attacker could use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-4300, CVE-2016-4302)

It was discovered that libarchive incorrectly handled memory allocation with large cpio symlinks. A remote attacker could use this issue to possibly cause libarchive to crash, resulting in a denial of service. (CVE-2016-4809)
