Vulnerability from csaf_redhat - Published: 2004-09-07 15:41 - Updated: 2025-11-21 17:27
Summary
Red Hat Security Advisory: lha security update
Severity
Important
Notes
Topic: An updated lha package that fixes a buffer overflow is now available.
Details: LHA is an archiving and compression utility for LHarc format archives. Lukasz Wojtow discovered a stack-based buffer overflow in all versions of lha up to and including version 1.14. A carefully created archive could allow an attacker to execute arbitrary code when a victim extracts or tests the archive. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0769 to this issue. Buffer overflows were discovered in the command line processing of all versions of lha up to and including version 1.14. If a malicious user can trick a victim into passing a specially crafted command line to the lha command, it is possible that arbitrary code could be executed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0771 and CAN-2004-0694 to these issues. Thomas Biege discovered a shell meta character command execution vulnerability in all versions of lha up to and including 1.14. An attacker could create a directory with shell meta characters in its name which could lead to arbitrary command execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0745 to this issue. Users of lha should update to this updated package which contains backported patches and is not vulnerable to these issues.

CVE-2004-0694

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.

CVE-2004-0769

Buffer overflow in LHA allows remote attackers to execute arbitrary code via long pathnames in LHarc format 2 headers for a .LHZ archive, as originally demonstrated using the "x" option but also exploitable through "l" and "v", and fixed in header.c, a different issue than CVE-2004-0771.

Buffer overflow in the extract_one function from lhext.c in LHA may allow attackers to execute arbitrary code via a long w (working directory) command line option, a different issue than CVE-2004-0769. NOTE: this issue may be REJECTED if there are not any cases in which LHA is setuid or is otherwise used across security boundaries.
