CVE Reference:
CVE-2010-0001
(Links to External Site)
|
Date: Jan 21 2010
|
Impact:
Execution of arbitrary code via network, User access via network
|
|
Version(s): 1.2.4
|
Description:
A vulnerability was reported in Gzip. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a specially crafted LZW compressed gzip archive that, when unzipped by the target user, will trigger an integer underflow and execute arbitrary code on the target system. The code will run with the privileges of the target user.

Subject: gzip
|
An integer underflow leading to array index error was found in the way
gzip used to decompress files / archives, compressed with the Lempel–Ziv–Welch
(LZW) compression algorithm. A remote attacker could provide a
specially-crafted LZW compressed gzip archive, which once decompressed
by a local, unsuspecting user would lead to gzip crash, or, potentially to
arbitrary code execution with the privileges of the user running gzip.
