USN-151-2: zlib vulnerabilities

Publication date

23 July 2005

Overview

zlib vulnerabilities

Releases

Details

USN-148-1 and USN-151-1 fixed two security flaws in zlib, which could
be exploited to cause Denial of Service attacks or even arbitrary code
execution with malicious data streams.

Most applications use the shared library provided by the “zlib1g”
package; however, some packages contain copies of the affected zlib
code, so they need to be upgraded as well.
