Synopsis ========
A buffer underflow vulnerability has been reported in ncompress allowing for the execution of arbitrary code.
Background ==========
ncompress is a suite of utilities to create and extract Lempel-Ziff-Welch (LZW) compressed archives.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/ncompress < 4.2.4.1 >= 4.2.4.1
Description ===========
Tavis Ormandy of the Google Security Team discovered a static buffer underflow in ncompress.
Impact ======
An attacker could create a specially crafted LZW archive, that when decompressed by a user or automated system would result in the execution of arbitrary code with the permissions of the user invoking the utility.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ncompress users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/ncompress-4.2.4.1"
