Synopsis ========
A buffer overflow in xdelta might allow remote attackers to execute arbitrary code.
Background ==========
Xdelta is a C library and command-line tool for delta compression using VCDIFF/RFC 3284 streams.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/xdelta < 3.0.10 >= 3.0.10
Description ===========
A buffer overflow can be triggered within xdelta when ran against a malicious input file.
Impact ======
A remote attacker could coerce the victim to run xdelta against a malicious input file. This may be leveraged by an attacker to crash xdelta and gain control of program execution.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All xdelta users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-util/xdelta-3.0.10"
References ==========
