- From advisory: |

|
20 |
"man 1.5l was released today, fixing a bug which results in arbitrary code |
21 |
execution upon reading a specially formatted man file. The basic problem |
22 |
is, upon finding a string with a quoting problem, the function my_xsprintf |
23 |
in util.c will return "unsafe" (rather than returning a string which could |
24 |
be interpreted by the shell). This return value is passed directly to |
25 |
system(3) - meaning if there is any program named `unsafe`, it will execute |
26 |
with the privs of the user." |
