+ <title>GNU C Library: Integer overflow</title>

+ An integer overflow in the dynamic loader, ld.so, could result in the

+ <background>
+ <p>
+ The GNU C library is the standard C library used by Gentoo Linux
+ systems. It provides programs with basic facilities and interfaces to
+ system calls. ld.so is the dynamic linker which prepares dynamically
+ linked programs for execution by resolving runtime dependencies and
+ related functions.

+ <description>
+ <p>
+ Tavis Ormandy of the Gentoo Linux Security Team discovered a flaw in
+ the handling of the hardware capabilities mask by the dynamic loader.
+ If a mask is specified with a high population count, an integer
+ overflow could occur when allocating memory.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ As the hardware capabilities mask is honored by the dynamic loader
+ during the execution of suid and sgid programs, in theory this
+ vulnerability could result in the execution of arbitrary code with root
+ privileges. This update is provided as a precaution against currently
+ unknown attack vectors.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=sys-libs/glibc-2.5-r4"</code>
