Description
When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the `CURLOPT_ACCEPT_ENCODING` option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow would make libcurl perform a buffer overflow.
Analysis
When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the CURLOPT_ACCEPT_ENCODING option, using zlib 1.2.0.3 or older, an attacker-controlled. Rated high severity (CVSS 7.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
Technical Context
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the `CURLOPT_ACCEPT_ENCODING` option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow would make libcurl perform a buffer overflow. Affected products include: Netapp Hci Baseboard Management Controller, Netapp Hci H610S Firmware, Netapp Hci H610C Firmware, Netapp Hci H615C Firmware, Netapp Solidfire \& Hci Management Node.
Affected Products
Netapp Hci Baseboard Management Controller, Netapp Hci H610S Firmware, Netapp Hci H610C Firmware, Netapp Hci H615C Firmware, Netapp Solidfire \& Hci Management Node.
Remediation
A vendor patch is available. Apply the latest security update as soon as possible. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
