From the CERT advisory: Overview: There is an integer overflow in the xdrmem_getbytes() function distributed as part of the Sun Microsystems XDR library. This overflow can cause remotely exploitable buffer overflows in multiple applications, leading to the execution of arbitrary code. Although the library was originally distributed by Sun Microsystems, multiple vendors have included the vulnerable code in their own implementations. GNU glibc: Version 2.3.1 of the GNU C Library is vulnerable. Earlier versions are also vulnerable. The following patches have been installed into the CVS sources, and should appear in the next version of the GNU C Library. These patches are also available from the following URLs: http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sunrpc/rpc/xdr.h.diff?r1=1.26&r2=1.27&cvsroot=glibc http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sunrpc/xdr_mem.c.diff?r1=1.13&r2=1.15&cvsroot=glibc http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sunrpc/xdr_rec.c.diff?r1=1.26&r2=1.27&cvsroot=glibc http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sunrpc/xdr_sizeof.c.diff?r1=1.5&r2=1.6&cvsroot=glibc http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sunrpc/xdr_stdio.c.diff?r1=1.15&r2=1.16&cvsroot=glibc
Martin, I've added glibc-2.3.1-r4 (copied from 2.3.1-r3) with the patches to the tree but I want your approval before I unmask it. Could you take a look and tell me what you think?
