Synopsis ========
Pngcrush is vulnerable to a buffer overflow which could potentially lead to the execution of arbitrary code.
Background ==========
Pngcrush is an optimizer for PNG files.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/pngcrush < 1.6.2 >= 1.6.2
Description ===========
Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a vulnerable version of zlib (GLSA 200507-19).
Impact ======
By creating a specially crafted data stream, attackers can overwrite data structures for applications that use Pngcrush, resulting in a Denial of Service and potentially arbitrary code execution.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Pngcrush users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.2"
