RH advisory:
  	

An updated lha package fixes security vulnerability
Advisory: 	RHSA-2004:323-09
Last updated on: 	2004-09-01
[...]

CVEs (cve.mitre.org):
CAN-2004-0694
CAN-2004-0745
CAN-2004-0769
CAN-2004-0771

Details:

An updated lha package that fixes a buffer overflow is now available.

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
could 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.

ok... didn't notice it was an errata by RedHat and it seems to have been dealt
with quite a while ago

*** This bug has been marked as a duplicate of 51285 ***

It doesn't appear to be a total duplicate. There are new OSVDB entries and the
CAN numbers look kinda new. And Red Hat is patching quite a bit more than the
ebuild does at the moment, if I am not mistaken again.

RH Patch1: lha-114i-sec.patch
not attached, because it's identical to Gentoo's lha-114i.diff

usata, you fixed it last time, could you have a look ?
We may have patched only part of the issues.

Yes, it looks another vulnerability. I added the patches to lha and released it
as lha-114i-r4.
Also I added =app-arch/lha-114i-r2 and =app-arch/lha-114i-r3 to p.mask.

Thanks usata, this is ready for yet another GLSA...
