CVSS v3.1 |
| When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. |
| A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. |
| curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. |
| A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. |
| The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v). |
| Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3. |
| An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers. |
| curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. |
| CUPS (Common Unix Printing System) 1.04 and earlier allows remote attackers to cause a denial of service via a malformed IPP request. |
| The debstd script in debmake 3.6.x before 3.6.10 and 3.7.x before 3.7.7 allows local users to overwrite arbitrary files via a symlink attack on temporary directories. |
| Memory leak in ProFTPd 1.2.0rc2 allows remote attackers to cause a denial of service via a series of USER commands, and possibly SIZE commands if the server has been improperly installed. |
| Buffer underflow in extfs.c in Midnight Commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code. |
| The Sendmail 8.12.3 package in Debian GNU/Linux 3.0 does not securely create temporary files, which could allow local users to gain additional privileges via (1) expn, (2) checksendmail, or (3) doublebounce.pl. |
| htdig allows remote attackers to execute commands via filenames with shell metacharacters. |
| The Debian mailman package uses weak authentication, which allows attackers to gain privileges. |
| Denial of service in Debian IRC Epic/epic4 client via a long string. |
| Kernel logging daemon (klogd) in Linux does not properly cleanse user-injected format strings, which allows local users to gain root privileges by triggering malformed kernel messages. |
| direntry.c in Midnight Commander (mc) 4.5.55 and earlier allows attackers to cause a denial of service by "manipulating non-existing file handles." |
| Heap-based buffer overflow in the ne_rfc1036_parse date parsing function for the neon library (libneon) 0.24.5 and earlier, as used by cadaver before 0.22, allows remote WebDAV servers to execute arbitrary code on the client. |
| Multiple integer overflows in (1) readbmp.c, (2) readgif.c, (3) readgif.c, (4) readmrf.c, (5) readpcx.c, (6) readpng.c,(7) readpnm.c, (8) readprf.c, (9) readtiff.c, (10) readxbm.c, (11) readxpm.c in zgv 5.8 allow remote attackers to execute arbitrary code via certain image headers that cause calculations to be overflowed and small buffers to be allocated, leading to buffer overflows. NOTE: CVE-2004-0994 and CVE-2004-1095 identify sets of bugs that only partially overlap, despite having the same developer. Therefore, they should be regarded as distinct. |
