Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Memory leak (CVE-ID: CVE-2020-9489)

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

A carefully crafted or corrupt file may trigger a System.exit in Tika's OneNote Parser. Crafted or corrupted files can also cause out of memory errors and/or infinite loops in Tika's ICNSParser, MP3Parser, MP4Parser, SAS7BDATParser, OneNoteParser and ImageParser. Apache Tika users should upgrade to 1.24.1 or later. The vulnerabilities in the MP4Parser were partially fixed by upgrading the com.googlecode:isoparser:1.1.22 dependency to org.tallison:isoparser:1.9.41.2. For unrelated security reasons, we upgraded org.apache.cxf to 3.3.6 as part of the 1.24.1 release.


2) Resource management error (CVE-ID: CVE-2019-12402)

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

The vulnerability exists due to the file name encoding algorithm can get into an infinite loop when faced with specially crafted inputs. A remote attacker can choose the file names inside of an archive created by Compress and cause a denial of service condition on the target system.


3) Resource exhaustion (CVE-ID: CVE-2020-11612)

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

The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
