An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

http://seclists.org/oss-sec/2016/q4/602

In ProFTPD 1.3.7, it is possible to corrupt the memory pool by interrupting the data transfer channel. This triggers a use-after-free in allocpool in pool.c, and possible remote code execution.

A flaw was found in microprocessor execution engine sharing on SMT (e.g. Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process, can extract certain secret information.

The reporter is able to steal an OpenSSL (<= 1.1.0h) P-384 private key from a TLS server using this new side-channel vector. It is a local attack in the sense that the malicious process must be running on the same physical core as the victim (an openSSL-powered TLS server in this case). But in general any application which branches on a secret value may be affected.

cdfreadpropertyinfo in cdf.c in file through 5.37 does not restrict the number of CDFVECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).

An issue was discovered in tlsverifycrl in ProFTPD through 1.3.6b. A dereference of a NULL pointer may occur. This pointer is returned by the OpenSSL skX509REVOKEDvalue() function when encountering an empty CRL installed by a system administrator. The dereference occurs when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.

An arbitrary file copy vulnerability in modcopy in ProFTPD up to 1.3.5b allows for remote code execution and information disclosure without authentication, a related issue to CVE-2015-3306.

A heap-based buffer overflow vulnerability was found in HTTP protocol handling, potentially allowing a code execution.

The retr.c:fdreadbody() function is called when processing OK responses. When the response is sent chunked, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fdread(). As fdread() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fdread() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer.

A stack-based buffer overflow vulnerability was found in HTTP protocol handling, potentially allowing a code execution.

The http.c:skipshortbody() function is called in some circumstances, such as when processing redirects. When the response is sent chunked, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fdread(). As fdread() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fdread() with a completely attacker controlled length argument.

A vulnerability was found in icoutils in extract.c. It is possible to access unallocated memory via wrestool while parsing maliciously crafted file which would make the application crash or possibly allow code execution.
