Summary

The _asn1_extract_der_octet function in lib/decoding.c in GNU Libtasn1 before 4.5 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a crafted certificate.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThe following packages have been upgraded to a later upstream version: libtasn1 (4.10). Security Fix(es) : - A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER- encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622) - A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library.

    descriptionAn update for libtasn1 is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Libtasn1 is a library that provides Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and structures management, and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding functions. The following packages have been upgraded to a later upstream version: libtasn1 (4.10). (BZ#1360639) Security Fix(es) : * A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622) * A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library. (CVE-2015-2806) Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.

    "An update for libtasn1 is now available for Red Hat Enterprise Linux
    7.
    
    Red Hat Product Security has rated this update as having a security
    impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
    score, which gives a detailed severity rating, is available for each
    vulnerability from the CVE link(s) in the References section.
    
    Libtasn1 is a library that provides Abstract Syntax Notation One
    (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and
    structures management, and Distinguished Encoding Rules (DER, as per
    X.690) encoding and decoding functions.
    
    The following packages have been upgraded to a later upstream version:
    libtasn1 (4.10). (BZ#1360639)
    
    Security Fix(es) :
    
    * A heap-based buffer overflow flaw was found in the way the libtasn1
    library decoded certain DER-encoded inputs. A specially crafted
    DER-encoded input could cause an application using libtasn1 to perform
    an invalid read, causing the application to crash. (CVE-2015-3622)
    
    * A stack-based buffer overflow was found in the way libtasn1 decoded
    certain DER encoded data. An attacker could use this flaw to crash an
    application using the libtasn1 library. (CVE-2015-2806)
    
    Additional Changes :
    
    For detailed information on changes in this release, see the Red Hat
    Enterprise Linux 7.4 Release Notes linked from the References section."

    descriptionFrom Red Hat Security Advisory 2017:1860 : An update for libtasn1 is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. Libtasn1 is a library that provides Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and structures management, and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding functions. The following packages have been upgraded to a later upstream version: libtasn1 (4.10). (BZ#1360639) Security Fix(es) : * A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622) * A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library. (CVE-2015-2806) Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.

    descriptionAccording to the versions of the libtasn1 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622) - A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library. (CVE-2015-2806) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
