Descriptions
Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows remote attackers to cause a denial of service (crash) via a crafted OID in a (1) S/MIME message or (2) ECC based OpenPGP data, which triggers a buffer overflow.
Desbordamiento de enteros en la función ksba_oid_to_str en Libksba anterior a 1.3.2, utilizado en GnuPG, permite a atacantes remotos causar una denegación de servicio (caída) a través de un OID manipulado en (1) un mensaje S/MIME o (2) datos OpenPGP basados en ECC, lo que provoca un desbordamiento de buffer.
An integer underflow flaw, leading to a heap-based buffer overflow, was found in the ksba_oid_to_str() function of libksba, an X.509 and CMS (PKCS#7) library. By using special crafted S/MIME messages or ECC based OpenPGP data, it is possible to create a buffer overflow, which could cause an application using libksba to crash (denial of service), or potentially, execute arbitrary code.
