Severity: High Title: Binary diff: Heap-based buffer overflow Date: March 19, 2020 Bugs: #701848 ID: 202003-44

Synopsis ========
A heap-based buffer overflow in Binary diff might allow remote attackers to execute arbitrary code.
Background ==========
bsdiff and bspatch are tools for building and applying patches to binary files.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/bsdiff < 4.3-r4 >= 4.3-r4
Description ===========
It was discovered that the implementation of bspatch did not check for a negative value on numbers of bytes read from the diff and extra streams.
Impact ======
A remote attacker could entice a user to apply a specially crafted patch using bspatch, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Binary diff users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-util/bsdiff-4.3-r4"
References ==========
