Description Josh Bressers 2005-03-30 14:16:09 UTC

Stack-based buffer overflow in shar in GNU sharutils 4.2.1 allows local users to
execute arbitrary code via a long -o command line argument.

To test this:
shar -o `perl -e 'print "A"x2000'`

A patch is located here:

Comment 1 Josh Bressers 2005-03-30 14:16:55 UTC

This issue also affects RHEL2.1

Comment 2 Ngo Than 2005-03-30 23:18:06 UTC

it's fixed in sharutils-4.2.1-8.8.x (rhel-2) and sharutils-4.2.1-16.1 (rhel3)

Comment 3 Jay Turner 2005-03-31 06:21:55 UTC

sharutils-4.2.1-16.1 is in 3.0E-errata-candidate
sharutils-4.2.1-8.8.x is in 2.1AS-errata-candidate

None of these have been released in errata, as the most recent errata was for
2.1 only and included sharutils-4.2.1-8.7.x.  Reopening this issue.

Comment 4 Than Ngo 2005-04-14 11:13:46 UTC

it's fixed in sharutils-4.2.1-8.9.x (rhel-2) and sharutils-4.2.1-16.2 (rhel3)
