Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2014-9636)

The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to out-of-bounds read when handling malicious input. A remote attacker can supply extra field with an uncompressed size smaller than the compressed field size in a zip archive that advertises STORED method compression and cause the service to crash.

2) Buffer overflow (CVE-ID: CVE-2014-9913)

The vulnerability allows a local non-authenticated attacker to perform service disruption.

Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via vectors related to the compression method.


3) Out-of-bounds read (CVE-ID: CVE-2015-7696)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in Info-ZIP UnZip 6.0. A remote attacker can perform a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.


4) Resource management error (CVE-ID: CVE-2015-7697)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2 data in a ZIP archive.


5) Input validation error (CVE-ID: CVE-2016-9844)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the zi_short() function in zipinfo.c when processing a large compression method value in the central directory file header. A remote attacker can pass a specially crafted array to the application and trigger denial of service (DoS) condition.


6) Heap-based buffer overflow (CVE-ID: CVE-2018-1000035)

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to heap-based buffer overflow in the processing of password-protected archives. A remote attacker can trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
