[GLSA-200507-05] zlib: Buffer overflow Vulnerability Scan
Vulnerability Scan Summary
zlib: Buffer overflow
Detailed Explanation for this Vulnerability Test
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
A possible hacker 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"
Threat Level: High
