Package: unzip
Version: 3.0-11+b1
Dear Maintainer,
I would like to report a security bug to zipnote binary of zip package
(zipinfo).
A segfault during the write operation with zipnote version 3.0
How to reproduce the bug :
1 - zipnote crash00.zip > note
2 - zipnote -w crash00.zip < note
The execution trace show a memcpy with the wrong size :
######################################
free(0x559aff234480)
= <void>
free(0x559aff2343a0)
= <void>
fclose(0x559aff234150)
= 0
ftello64(0x559aff233280, 1, 0, 0x559aff233010)
= 124
malloc(1)
= 0x559aff234480
memcpy(0x559aff234480, "", 0)
= 0x559aff234480
memcpy(0x559aff234480,
"mples/UT\005\0\177\0\0\0\0\0\0\0\0\0\0\301\0\0\0\0\0\0\0\036\003\n"...,
