GLSA-200507-05 : zlib: Buffer overflow

high Nessus Plugin ID 18634

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200507-05 (zlib: Buffer overflow)

 Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a buffer overflow in zlib. A bounds checking operation failed to take invalid data into account, allowing a specifically malformed deflate data stream to overrun a buffer.
 Impact :

 An attacker could construct a malformed data stream, embedding it within network communication or an application file format, potentially resulting in the execution of arbitrary code when decoded by the application using the zlib library.
 Workaround :

 There is no known workaround at this time.

Solution

All zlib users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=sys-libs/zlib-1.2.2-r1'
