Recommended Posts

Multiple vulnerabilities has been found and corrected in ghostscript:

 

Buffer overflow in gs/psi/iscan.c in Ghostscript 8.64 and earlier

allows remote attackers to execute arbitrary code or cause a denial

of service (memory corruption) via a crafted PDF document containing

a long name (CVE-2009-4897).

 

Ghostscript 8.64, 8.70, and possibly other versions allows

context-dependent attackers to execute arbitrary code via a

PostScript file containing unlimited recursive procedure invocations,

which trigger memory corruption in the stack of the interpreter

(CVE-2010-1628).

 

As a precaution ghostscriptc has been rebuilt to link against the

system libpng library which was fixed with MDVSA-2010:133

 

The updated packages have been patched to correct these issues.
