Summary
It was discovered that curl incorrectly reused client certificates when
built with NSS. A remote attacker could possibly use this issue to hijack
the authentication of a TLS connection. (CVE-2016-7141)
Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain
strings. A remote attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2016-7167)
It was discovered that curl incorrectly handled storing cookies. A remote
attacker could possibly use this issue to inject cookies for arbitrary
domains in the cookie jar. (CVE-2016-8615)
It was discovered that curl incorrect handled case when comparing user
names and passwords. A remote attacker with knowledge of a case-insensitive
version of the correct password could possibly use this issue to cause
a connection to be reused. (CVE-2016-8616)
It was discovered that curl incorrect handled memory when encoding to
base64. A remote attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2016-8617)
It was discovered that curl incorrect handled memory when preparing
formatted output. A remote attacker could possibly use this issue to cause
curl to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2016-8618)
It was discovered that curl incorrect handled memory when performing
Kerberos authentication. A remote attacker could possibly use this issue to
cause curl to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2016-8619)
Luật Nguyễn discovered that curl incorrectly handled parsing globs. A
remote attacker could possibly use this issue to cause curl to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.
(CVE-2016-8620)
Luật Nguyễn discovered that curl incorrectly handled converting dates. A
remote attacker could possibly use this issue to cause curl to crash,
resulting in a denial of service. (CVE-2016-8621)
It was discovered that curl incorrectly handled URL percent-encoding
decoding. A remote attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2016-8622)
It was discovered that curl incorrectly handled shared cookies. A remote
server could possibly obtain incorrect cookies or other sensitive
information. (CVE-2016-8623)
Fernando Muñoz discovered that curl incorrect parsed certain URLs. A remote
attacker could possibly use this issue to trick curl into connecting to a
different host. (CVE-2016-8624)
