A vulnerability in Pngcrush might result in user-assisted execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/pngcrush | * | < 1.6.4-r1 | >= 1.6.4-r1 |
Pngcrush is a multi platform optimizer for PNG (Portable Network Graphics) files.
It has been reported that Pngcrush includes a copy of libpng that is vulnerable to a memory corruption (GLSA 200804-15).
A remote attacker could entice a user to process a specially crafted PNG image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
All Pngcrush users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.4-r1"
Pngcrush is vulnerable to a buffer overflow which could potentially lead to the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/pngcrush | * | < 1.6.2 | >= 1.6.2 |
Pngcrush is an optimizer for PNG files.
Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a vulnerable version of zlib (GLSA 200507-19).
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.
There is no known workaround at this time.
All Pngcrush users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.2"
