Mandrake Richard Kettlewell discovered a buffer overflow vulnerability in the zlib library's gzprintf() function.


                Mandrake Linux Security Update Advisory

Package name:           zlib
Advisory ID:            MDKSA-2003:033
Date:                   March 18th, 2003

Affected versions:	7.2, 8.0, 8.1, 8.2, 9.0, Corporate Server 2.1,
			Multi Network Firewall 8.2,
			Single Network Firewall 7.2

Problem Description:

 Richard Kettlewell discovered a buffer overflow vulnerability in the 
 zlib library's gzprintf() function.  This can be used by attackers 
 to cause a denial of service or possibly even the execution of 
 arbitrary code.  Our thanks to the OpenPKG team for providing a patch
 which adds the necessary configure script checks to always use the
 secure vsnprintf(3) and snprintf(3) functions, and which additionally
 adjusts the code to correctly take into account the return value of
 vsnprintf(3) and snprintf(3).
