CVE-2021-36159

libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. The FTP passive mode implementation allows an out-of-bounds read because strtol is used to parse the relevant numbers into address bytes. It does not check if the...

Denial Of Service (DoS)

libcurl.so is vulnerable to denial of service DoS. The vulnerability is possible because it does not properly handle the end-of-response for SMTP, leading to an out-of-bounds read if the strtol function is called. Therefore, it causes reading beyond the allocated buffer...

CVE-2019-3823

libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to smtpendofresp isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol call rea...

SMTP end-of-response out-of-bounds read

libcurl contains a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to smtpendofresp is not null-terminated and contains no character ending the parsed number, and len is set to 5, then the strtol call reads beyond the allocated buffer. The read...

CVE-2017-13090

The connected documents confirm CVE-2017-13090 affects wget prior to 1.19.2, due to chunked HTTP processing in retr.c:fd_read_body(). The chunk parser uses strtol() to read chunk lengths but does not validate non-negativity; then reads chunks with MIN(..) and passes a negative length to fd_read()...
