Title
Cisco AnyConnect Secure Mobility Client for Linux Out-of-Bounds Memory Read Vulnerability
Summary
A vulnerability in the HostScan component of Cisco AnyConnect Secure Mobility Client for Linux could allow an unauthenticated, remote attacker to read sensitive information on an affected system. The vulnerability exists because the affected software performs improper bounds checks. An attacker could exploit this vulnerability by crafting HTTP traffic for the affected component to download and process. A successful exploit could allow the attacker to read sensitive information on the affected system.

CVE-2019-3557 (GCVE-0-2019-3557)
Vulnerability from cvelistv5 – Published: 2019-01-15 22:00 – Updated: 2024-08-04 19:12
VLAI
Summary
The implementations of streams for bz2 and php://output improperly implemented their readImpl functions, returning -1 consistently. This behavior caused some stream functions, such as stream_get_line, to trigger an out-of-bounds read when operating on such malformed streams. The implementations were updated to return valid values consistently. This affects all supported versions of HHVM (3.30 and 3.27.4 and below).
Severity
No CVSS data available.

CVE-2019-3823 (GCVE-0-2019-3823)
Vulnerability from cvelistv5 – Published: 2019-02-06 20:00 – Updated: 2026-04-15 20:52
VLAI
Summary
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.
Severity

Mitigation ID: MIT-5
Phase: Implementation
Strategy: Input Validation
Description:
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Phase: Architecture and Design
Strategy: Language Selection
Description:
- Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
