iconv: ISO-2022-CN-EXT: fix out-of-bound writes when writing escape sequence (CVE-2024-2961)

2024-04-17T12:21:40Z

ISO-2022-CN-EXT uses escape sequences to indicate character set changes (as specified by RFC 1922). While the SOdesignation has the expected bounds checks, neither SS2designation nor SS3designation have its; allowing a write overflow of 1, 2, or 3 bytes with fixed values: '$+I', '$+J', '$+K', '$+L', '$+M', or '$*H'. Checked on aarch64-linux-gnu. Co-authored-by: Adhemerval Zanella Reviewed-by: Carlos O'Donell Tested-by: Carlos O'Donell

Replace rawmemchr (s, '\0') with strchr

2023-02-06T16:16:19Z

Almost all uses of rawmemchr find the end of a string. Since most targets use a generic implementation, replacing it with strchr is better since that is optimized by compilers into strlen (s) + s. Also fix the generic rawmemchr implementation to use a cast to unsigned char in the if statement. Reviewed-by: Adhemerval Zanella

iconvdata/tst-table-charmap.sh: remove handling of old, borrowed format

2022-11-09T12:48:46Z

This "Old POSIX/DKUUG borrowed format" handling is original to the file and doesn't seem to have ever been used, i.e. id/t-t-c doesn't seem to have ever been called with argv[1] == POSIX. Upcoming is a POSIX charmap, which would inadvertently trigger this. Signed-off-by: Ahelenia Ziemiańska Reviewed-by: Florian Weimer
