Summary

Stack-based buffer overflow in the server in IBM Tivoli Storage Manager FastBack 6.1 before 6.1.12 allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors, a different vulnerability than CVE-2015-1924, CVE-2015-1925, CVE-2015-1929, CVE-2015-1930, CVE-2015-1948, CVE-2015-1953, CVE-2015-1954, CVE-2015-1962, CVE-2015-1963, and CVE-2015-1964.

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 version of IBM Tivoli Storage Manager FastBack running on the remote host is 6.1.x prior to 6.1.12. It is, therefore, affected by multiple vulnerabilities : - An overflow condition exists due to improper validation of user-supplied input when handling opcode 1331. A remote, unauthenticated attacker can exploit this issue to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1923) - An overflow condition exists due to improper validation of user-supplied input when handling opcode 1329. A remote, unauthenticated attacker can exploit this issue to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1924) - An overflow condition exists due to improper validation of user-supplied input when handling opcode 1332. A remote, unauthenticated attacker can exploit this issue to cause an overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1925) - A buffer overflow condition exists in the FXCLI_OraBR_Exec_Command() function due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to cause a stack-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. (CVE-2015-1929) - A buffer overflow condition exists in the JOB_S_GetJobByUserFriendlyString() function due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to cause a stack-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. (CVE-2015-1930) - An overflow condition exists due to improper validation of user-supplied input when handling opcode 1331. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to execute arbitrary commands with a system call. (CVE-2015-1938) - An unspecified flaw exists that occurs during the handling of opcode 1329. A remote, unauthenticated attacker can exploit this issue to gain access to arbitrary files. (CVE-2015-1941) - An unspecified flaw exists that occurs during the handling of opcode 1332. A remote, unauthenticated attacker can exploit this issue to write or execute arbitrary files. (CVE-2015-1942) - An overflow condition exists due to improper validation of user-supplied input when handling opcode 1364. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1948) - An unspecified flaw exists that is triggered during the handling of opcode 1330. A remote, unauthenticated attacker can exploit this issue, via specially crafted packet, to execute arbitrary commands with a system call. (CVE-2015-1949) - A format string flaw exists in the vsprintf() function due to improper sanitization of user-supplied format string specifiers when processing opcode 1335. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-1953) - An overflow condition exists due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

(CVE-2015-1962) - An overflow condition exists due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1963) - An overflow condition exists due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1964) - An overflow condition exists due to improper validation of user-supplied input. A remote, unauthenticated attacker can exploit this issue to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-1965) - A format string flaw exists in the vsprintf() function due to improper sanitization of user-supplied format string specifiers when processing opcode 1301. A remote, unauthenticated attacker can exploit this issue, via a specially crafted packet, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-1986) - Multiple stack-based buffer overflow conditions exist due to improper bounds checking. A remote attacker can exploit these, via a crafted packet, to crash the server or execute arbitrary code with SYSTEM privileges. (CVE-2016-0212, CVE-2016-0213, CVE-2016-0216)
