Otkriven je sigurnosni propust programske biblioteke libotr koji omogućuje udaljenom napadaču izvođenje napada uskraćivanjem usluge ili pokretanje proizvoljnog programskog koda.
Paket:
libotr 3.x
Operacijski sustavi:
Debian Linux 6.0 (squeeze), Debian Linux sid (unstable), Debian Linux wheezy (testing)
Propusti su posljedica višestrukih preljeva međuspremnika u Base64 dekoderu.
Posljedica:
Propust je moguće iskoristiti za izvođenje DoS napada ili pokretanje proizvoljnog programskog koda podmetanjem posebno oblikovane poruke aplikacijama koje u svom radu koriste ranjivu biblioteku.

Package : libotr
Vulnerability : heap-based buffer overflows
Problem type : remote
Debian-specific: no
Debian bug : 684121
CVE ID : CVE-2012-3461
Just Ferguson discovered that libotr, an off-the-record (OTR) messaging
library, can be forced to perform zero-length allocations for heap buffers
that are used in base64 decoding routines. An attacker can exploit this
flaw by sending crafted messages to an application that is using libotr to
perform denial of service attacks or potentially execute arbitrary code.
For the stable distribution (squeeze), this problem has been fixed in
version 3.2.0-2+squeeze1.
For the testing distribution (wheezy), this problem has been fixed in
version 3.2.1-1.
For the unstable distribution (sid), this problem has been fixed in
version 3.2.1-1.
We recommend that you upgrade your libotr packages.
