CVE-2016-8622

The URL percent-encoding decode function in libcurl before 7.51.0 is called curleasyunescape. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get...

ALPINE-CVE-2016-8618

The libcurl API function called curlmaprintf before version 7.51.0 can be tricked into doing a double-free due to an unsafe sizet multiplication, on systems using 32 bit sizet variables...

CVE-2016-8622

CVE-2016-8622 affects curl/libcurl’s URL percent-encoding decode path. The curl_easy_unescape function may allocate a destination buffer larger than 2 GB but store the result length in a signed 32‑bit int, causing length truncation or negative values. This can lead to writing outside the heap. Pu...

CVE-2016-8618

The CVE-2016-8618 vulnerability affects libcurl’s curl_maprintf() and can be exploited to trigger a double-free due to an unsafe size_t multiplication on 32-bit size_t systems. The issue is addressed by upgrading to curl version 7.51.0 (upstream) or applying the patch. The Debian/Ubuntu advisorie...

Denial Of Service (DoS) Through Use-After-Free (UAF)

libcurl.so is vulnerable to denial of service DoS attacks through a use-after-free UAF bug. The use-after-free vulnerability is caused when libcurl leaves a dangling pointer to a freed connection struct, causing a DoS attack...

Denial Of Service (DoS)

libcurl.so is vulnerable to denial of service DoS attacks. A malicious user can pass a date string to parse to cause an out-of-bounds read, crashing the application...

Use-After-free Vulnerability

libcurl.so is vulnerable to use after-free vulnerability. The attack is possible when cookies are shared among many easy handles simultaneously used in different threads...

Buffer Overflow

libcurl.so is vulnerable to buffer overflows. The application does not properly allocate memory when decoding URL percent-encoding, allowing a malicious user to send a large URL to cause a buffer overflow, crash the application or causing arbitrary code to be executed...

CVE-2017-7468

In curl and libcurl 7.52.0 to and including 7.53.1, libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which...
