[GLSA-200611-24] LHa: Multiple vulnerabilities Vulnerability Scan
Vulnerability Scan Summary
LHa: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200611-24
(LHa: Multiple vulnerabilities)
Tavis Ormandy of the Google Security Team discovered several
vulnerabilities in the LZH decompression component used by LHa. The
make_table function of unlzh.c contains an array index error and a
buffer overflow vulnerability. The build_tree function of unpack.c
contains a buffer underflow vulnerability. Additionally, unlzh.c
contains a code that could run in an infinite loop.
By enticing a user to uncompress a specially crafted archive, a remote
attacker could cause a Denial of Service by CPU consumption or execute
arbitrary code with the rights of the user running the application.
There is no known workaround at this time.
All LHa users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/lha-114i-r6"
Threat Level: Medium
