Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Jason Self has reported a security issue in Mac OS X, which can be exploited by malicious people to bypass certain security restrictions.

The security issue is caused due to the Perl binary included with Mac OS X not correctly dropping privileges when a Perl application uses the "$< = numeric_id;" statement to set its uid. The issue may be caused due to wrong compilation options being selected when compiling the Perl binary.

The security issue has been reported in the Perl binary included with Mac OS X Server 10.3.9. Prior versions may also be affected.

Note: The actual impact depends on how a Perl application is written to use the affected Perl functionality.
