An integer overflow in GPL Ghostscript may allow remote attackers to execute arbitrary code.
|Package||app-text/ghostscript-gpl on all architectures|
|Affected versions||< 9.09|
|Unaffected versions||>= 9.09|
Ghostscript is an interpreter for the PostScript language and for PDF.
An integer overflow flaw was discovered that leads to an out-of-bounds read and write in gs_ttf.ps.
A remote attacker could entice a user to open a specially crafted file, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All GPL Ghostscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-9.09"
