[原文]Buffer overflow in LHA 1.14 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors related to "command line processing," a different vulnerability than CVE-2004-0771. NOTE: this issue may be REJECTED if there are not any cases in which LHA is setuid or is otherwise used across security boundaries.

|LHA Unspecified Command Line Overflow|
|Local Access Required||Input Manipulation|
|Loss of Confidentiality, Loss of Integrity|
|A local overflow exists in LHA. LHA fails to perform proper bounds checking on command line arguments resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary commands resulting in a loss of confidentiality and/or integrity.|
|Upgrade to version LHA for UNIX Version 1.14i or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.|

Mr. S.K. LHA 1.14
|LHA is reported prone to multiple vulnerabilities. These issues include multiple local and remote buffer overflow vulnerabilities and a remote command execution vulnerability. Successful exploitation of these issues may allow an attacker to execute arbitrary code and gain unauthorized access to a vulnerable computer.
The following specific issues were reported:
The application is prone to a stack overflow vulnerability when processing a malicious archive.
Multiple local buffer overflow vulnerabilities were reported as well. These issues can be triggered by supplying an excessive string value to the application through the command line.
Additionally, a remote command execution issue affects the application. This issue is triggered when LHA processes a directory with a malformed name.
LHA versions 1.14 and prior are affected by these issues.
Currently we are not aware of any exploits for this issue. If you feel we are in error or are aware of more recent information, please mail us at: email@example.com <mailto:firstname.lastname@example.org>.
RedHat has released an advisory (RHSA-2004:323-09) to address these issues. Please see the advisory in Web references for more information.
RedHat has released an advisory (RHSA-2004:440-04) along with fixes to address these issues for RedHat Enterprise Linux operating systems. Please see the referenced advisory for further information.
