RHSA-2005:659 - Security Advisory

Topic

An updated binutils package that fixes several bugs and minor security
issues is now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

Binutils is a collection of utilities used for the creation of executable
code. A number of bugs were found in various binutils tools.

Several integer overflow bugs were found in binutils. If a user is tricked
into processing a specially crafted executable with utilities such as
readelf, size, strings, objdump, or nm, it may allow the execution of
arbitrary code as the user running the utility. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1704
to this issue.

Additionally, the following bugs have been fixed:

• - correct alignment of .tbss section if the requested alignment

of .tbss is bigger than requested alignment of .tdata section

• - by default issue an error if IA-64 hint@pause instruction is

put into the B slot, add assembler command line switch to
override this behaviour

All users of binutils should upgrade to this updated package, which
contains backported patches to resolve these issues.
