Description Josh Bressers 2005-07-12 13:46:48 UTC

A buffer overflow issue has been found in zlib that can overflow
inflate_state.codes[ENOUGH] by 16 bytes.

It is possible to leverage this issue by creating a valid zlib stream.

Comment 1 Josh Bressers 2005-07-12 13:48:03 UTC

This issue does not affect RHEL2.1 or RHEL3

Comment 2 Mark J. Cox 2005-07-21 17:35:44 UTC

This has been made public at least in a Debian update yesterday, so removing
embargo from the bug.
