zlib: Buffer overflow

zlib: Buffer overflow zlib is vulnerable to a buffer overflow which could potentially lead to execution of arbitrary code. zlib 2005-07-22 2005-07-22: 01 99751 remote 1.2.3 1.2.3

zlib is a widely used free and patent unencumbered data compression library.

zlib improperly handles invalid data streams which could lead to a buffer overflow.

By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use zlib, resulting in arbitrary code execution or a Denial of Service.

There is no known workaround at this time.

All zlib users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-libs/zlib-1.2.3"
