Picasm is affected by a remote buffer overflow vulnerability.
|
|
|
|
An attacker can exploit this issue by supplying an excessive 'error' directive.
|
|
|
|
If successfully exploited, this issue can allow a remote attacker to gain access to the affected computer in the context of the user running the application.
|
|
|
|
Picasm 1.12b and prior versions are vulnerable to this issue.

/* picasm_exploit.c - by Shaun Colley <shaun rsc cx>
|
|
*
|
|
* This code generates a picasm source file with a malformed 'error' directive,
|
|
* which exploits a stack overflow vulnerability in picasm's error printing
|
|
* routines. The file generated by this exploit will only cause execution
|
|
* of FreeBSD 'reboot()' shellcode. Exploit has been tested on
|
|
FreeBSD 5.3-RELEASE.
|
|
* Return address into shellcode may need changing on other operating system
|
|
* versions. Other shellcodes can potentially be used instead of the
|
|
one below.
|
|
*
|
|
* A fix has been provided by picasm's maintainer. The fixed packages can be
|
|
* found at <http://www.co.jyu.fi/~trossi/pic/picasm112c.tar.gz>.
