All supported architectures
A heap overflow in mpg123 was discovered, which could result in the
execution of arbitrary code.
mpg123 is a real time audio player designed for the MPEG format.
In httpdget.c, a variable is assigned to the heap, and is supposed to
receive a smaller allocation. As this variable was not terminated
properly, strncpy() will overwrite the data assigned next in memory.
By enticing a user to visit a malicious URL, an attacker could possibly
execute arbitrary code with the rights of the user running mpg123.
There is no known workaround at this time.
All mpg123 users should update to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r11"
