TITLE:
Lhaz LZH File Handling Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA21348

VERIFY ADVISORY:
http://secunia.com/advisories/21348/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Lhaz 1.x
http://secunia.com/product/11242/

DESCRIPTION:
Tan Chew Keong has reported two vulnerabilities in Lhaz, which can be
exploited by malicious people to compromise a user's system.

1) A boundary error when extracting LZH files can be exploited to
cause a stack-based buffer overflow when attempting to extract a
specially crafted LZH file containing a compressed file with an
overly long filename (more than 260 bytes).

This is related to:
SA11510
SA12435

2) A boundary error exists during the construction of an error
message when attempting to extract an invalid LZH file. This can be
exploited to cause a stack-based buffer overflow when a specially
crafted LZH file with an invalid CRC checksum is extracted.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

The vulnerabilities have been reported in version 1.31 (Japanese).
Prior versions may also be affected.

SOLUTION:
Update to version 1.32.

PROVIDED AND/OR DISCOVERED BY:
Tan Chew Keong
