Gentoo Linux Security Advisory
Title: sharutils: Buffer overflows in shar.c and unshar.c (GLSA 200410-01)
Severity: normal
Exploitable: remote
Date: October 01, 2004
Updated: May 22, 2006
Bug(s): #65773
ID: 200410-01
Synopsis
sharutils contains two buffer overflow vulnerabilities that could lead to
arbitrary code execution.
Background
sharutils contains utilities to manage shell archives.
Affected Packages
Package: app-arch/sharutils
Vulnerable: <= 4.2.1-r9
Unaffected: >= 4.2.1-r10
Architectures: All supported architectures
Description
sharutils contains two buffer overflows. Ulf Harnhammar discovered a
buffer overflow in shar.c, where the length of data returned by the wc
command is not checked. Florian Schilhabel discovered another buffer
overflow in unshar.c.
Impact
An attacker could exploit these vulnerabilities to execute arbitrary
code as the user running one of the sharutils programs.
Workaround
There is no known workaround at this time.
Resolution
All sharutils users should upgrade to the latest version:
Code: | # emerge sync
# emerge -pv ">=app-arch/sharutils-4.2.1-r10"
# emerge ">=app-arch/sharutils-4.2.1-r10" |
